WINNER Phase II channel model reference implementation _______________________________________________________________ version 0.64 (22.9.2008 Lassi) - New document WIM2 Matlab documentation V0.4.pdf created! - Updated files: almost every file updated slightly - Ansi_c support removed _________________________________________________________________ version 0.63 (12.2.2008 Pekka) pathloss.m -Error in D1 NLOS path loss formula corrected on row 433. The same error was also in WINNER deliverable D1.1.2 ver 1.1, but is corrected to version 1.2. __________________________________________________________________ version 0.62 with a new 3D antenna support (18.12.2007 Lassi) Please see "3D-Antenna-Array-Model.doc" for detailed information of the new 3d-feature. The feature is implemented by TU Ilmenau, please contact Martin Käske and Milan Narandzic for more information Changed files: LScorrelation.m, generate_bulk_par.m, layout2link.m, layoutparset.m, wim.m and wim_core.m Some general notes: -antparset.m does not work any more, use arrayparset.m instead to get some example arrays -with AntennaArray.m any kind of antenna geometry and field patterns can be generated -also, you can load Arrays.mat which includes a simple array with isotropic antennas -use layoutparset.m and layout2link.m to get linkpar e.g. linkpar = layout2link(layoutparset(1,1,1,Arrays)); ___________________________________________________________________ version 0.62 (12.11.2007 Pekka) linkparset.m, layoutparset.m, layout2link.m -parameter WallLoss removed -parameter NumPenetratedFloors added ___________________________________________________________________ version 0.61 (8.11.2007 Pekka, Mikko) generate_bulk_par.m -rows 393-421 modified ___________________________________________________________________ version 0.60 (18.10.2007 Mikko) LScorrelation.m -row 175 modified generate_bulk_par.m -row 278 modified ___________________________________________________________________ version 0.59 (10.10.2007 Pekka, Lassi) General note: Most of the modification / updates are due to the D1.1.2. Modified m-files: wim.m -corrected a bug related to use of initial values instead of bulk parameter generation on line 226 and 230 -corrected a bug on line 536 related to determination of variable SubClustInd wim_core.m -rows 412-413 modified wimparset.m -PathLossOption modified ScenParTables.m -changed according to the D1.1.2 linkparset.m - wall loss removed - numPenetratedFloors added struct_generation.m -row 27 updated since k-factor is now a LS-parameter. -rows 62-63, 36-37 and 77-78 modified since XPRv and XPRh unified ScenarioMapping.m -C4 added LScorrelation.m -K-factor definition changed according to the D1.1.2 --> modified rows: 51, 96, 101, 103, 107, 115, 124, 138-151, 165-166, 176, 185 generate_bulk_par.m -B2 delay generation changed equal to B1 NLOS (rows 247-267) -added if condition to STEP 3. If PathLossModelUsed='no', path loss is not generated at all. -K-factor definition changed according to the D1.1.2 (rows 225 and 277) -due to adding of scenario C4, rows 67, 132, 157, 166 and 239 updated -rows 536-563 and 767-794 modified since XPRv and XPRh unified pathloss.m -added checking of PL range lower limit on rows 47-48 and 55-56 -path loss functions updated based on the D1.1.2 fixedAoas.m, fixedAods.m, fixedPdp.m -updated CDL parameters based on WINNER final channel models D1.1.2 LOSprobability.m -C2 added ___________________________________________________________________ version 0.58 (17.08.2007 Pekka) Modified m-files: generate_bulk_par.m -corrected a bug related to combination of LOS and FixedPDP on line 506 wim.m -corrected an error related to use of initial values in the wim call, lines 221-237 added LScorrelation.m -lines 94-97 fixed 94 gridn = randn(max(MsXY(2,tmpMs))-min(MsXY(2,tmpMs))+2*xtra+1,... 95 max(MsXY(1,tmpMs))-min(MsXY(1,tmpMs))+2*xtra+1 ,4); 96 % Index to MS locations on the grid 97 gind = sub2ind(size(gridn),MsXY(2,tmpMs)-min(MsXY(2,tmpMs))+xtra+1,MsXY(1,tmpMs)-min(MsXY(1,tmpMs))+xtra+1); indexing is now performed by substracting min(MsXY(1,tmpMs)) from the actual MsXY. Please note the „+1“. Consider the case were max_x==2 and min_x==1 then max_x-min_x equals 1 but we need 2 samples from randn (one for max_x one for min_x, leave out 2*xtra). The same ist true for sub2ind, if we want to find the index for the mobile at min_x, we need the „xtra+1“’th element of the grid not the xtra’th (that would happen in the old code). ___________________________________________________________________ version 0.57 (06.07.2007 Lassi) Modified m-files: pathloss.m -added B1_NLOS_PL function 422-> -added a function function B1_NLOS_PL to rows 422-440 and lines 197-199 to confirm reciprocity in B1NLOS pathloss 197 loss_a = B1_NLOS_PL(Dist1,Dist2,loss_LoS,NLoSConnectionLinks,PL_bp,iterpar,CenterFrequency,wimpar,StreetWidth,H_bs,H_ms); 198 loss_b = B1_NLOS_PL(Dist2,Dist1,loss_LoS,NLoSConnectionLinks,PL_bp,iterpar,CenterFrequency,wimpar,StreetWidth,H_bs,H_ms); 199 loss(NLoSConnectionLinks) = min(loss_a(NLoSConnectionLinks),loss_b(NLoSConnectionLinks)); ___________________________________________________________________ Version 0.56 (21.06.2007 Pekka, Lassi) Modified m-files: LScorrelation.m -minor bug corrected on line 112 pathloss.m -small tuning: set error if MsBsDistance exceeds the maximum allowed cell radius ___________________________________________________________________ Version 0.55 (13.06.2007 Pekka) Modified m-files: LScorrelation.m -Auto-correlation generation changed to 2D- filtering of grid of samples (based on Per Zetterberg's original proposal). Cross correlation generation cleaned to simple linear transformation (multiplication by R^0.5). Distribution transformations simplified, all distributions are log-Normal in WINNER II. NTlayout.m - clf command added to row 46 to prevent plotting on top of the old figure ___________________________________________________________________ Version 0.54 (04.06.2007, Mikko, Lassi, Pekka) Modified m-files: layoutparset.m - Added new (linkpar) parameters ScenarioVector, PropagConditionVector, NumFloors - Changed determination of MsHeight, BsHeight, MsVelocity and MsDirection parameters layout2link.m - Added new (linkpar) parameters ScenarioVector, PropagConditionVector, NumFloors - Changed determination of MsHeight, BsHeight, MsVelocity and MsDirection parameters generate_bulk_par.m - Powers for LoS cases apply Ricean K-values. This is correct for the determination of the azimuth angles. However, for the powers saved in bulk_parameteres –struct this is not correct. - Ricean K factors are taken into account later in the generate_H.m function. Changes accordingly are done in lines 360 and 516-518. K-factors can take negative values and as long as the use of correction factor D is valid, this is not good (delays are negative as well). Hence, the Ricean K-factor is limited to 0dB. Changes accordingly in lines 226-229. Probably not needed after the K-factor is drawn from the distribution. - Bad urban: • All of the users exhibit bad urban effect (long delay). MsBsDist -distances are doubled. Changes accordingly in lines 202-217. • Every occurrence of SF… changed to FS… (far scatter). Not sure where SF came from. • Last two delays for every user are put to MsBsScatDist/3e8 in the output delays. Changes accordingly in lines 293-295. - Added rows 230-232 to restrict the K-factor below 20dB - Removed the validity check of MsBsDistance (rows 187-198) --> moved to pathloss.m (rows 45-47) ScenParTables.m - Takes StreetWidth as input. - D1 LoS AS_D_mu and AS_A_mu changed according to D111. - A2/B4 values updated according to the combined scenario in the draft of D112. Both scenarios are still left
