Zero Forcing equalization is the simplest method to estimate the transmitted symbols in a MIMO system using linear space time coding (See reference [1] for the theoretical background). For particular codes (orthogonal codes), ZF equalizer gives the same results than the optimal (ML) receiver.
The zip file contains three m files.
- space_time_coding.m (perform space time coding)
- coherent_ZF_receiver.m (perform ZF space time equalization)
- one_shot_ZF_equalizer.m (show an example)
To use these files, extract the three files in the same folder. Then, call the script one_shot_ZF_equalizer in the matlab command window. See the file space_time_coding.m to obtain the list of supported STBCs.
