##### Code updates June 21th 2021: This design has been obtained by making additions on a ready-made code. runsim_2.m and waterfilling.m files have been added to the existing codes. Updated files are rx_estimate_channel.m, rx_gen_chan_amps.m, receiver.m, single_packet.m, and runsim.m . ##### Programme The simulator GUI is started with command 'ui_start' in Matlab command window. WLAN simulation starts by clicking the 'Start Simulation' button in the GUI window. WLAN simulation can be terminated, before set number of packets have been reached by pressing 'control-C'. ##### Version updates and bug fixes January 24th 2002: A bug in file rx_qpsk_demod.m fixed July 31th 2002: A bug in file rx_gen_chan_amps.m fixed. This bug affected performance in fading channels. April 15th 2003: Changed the code not to require functions from the Matlab Communications toolbox.
