Blind Channel estimation for MIMO systems using Linear Space time codes

Perform channel estimation for general STBC-MIMO systems using a subspace approach.

The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files.

- space_time_coding.m (perform space time coding)
- subspace_channel_estimation_STBC.m (channel estimation)
- one_shot.m (show an example)

To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window.
