# Time offsets in MIMO OFDM Systems
This repository includes the codes used for the FYP titled: **Time offsets in MIMO OFDM Systems**
The final versions of the simulations are named below and can be run using MATLAB 2017b.
## Final MATLAB Scripts
results_SISO_v1.m
results_MISO_v1.m
results_MIMO_v1.m
results_MIMO_OFDMA_v1.m
## Instructions
To test the different systems open MATLAB and run the scripts. Different time offsets can be changed inside the simulation under the variable **delay11** or **delay12** or **delay21** or **delay22** to get different results and to view the sensitivity of the system to these time offsets.
## Findings
It was found that the cyclic prefix in these systems were able to absorb the time offset up to the length of the cyclic prefix. A time offset larger than the set cyclic prefix would reduce the performance of the system and introduce errors. A MIMO system is more robust against these impairments than a SISO system.
### Edits
Inside the folder **all code** are all the versions and edits used to create the scripts above.
