The channel estimation algorithm is based on Second Order Statistics. The method works only for SOS-identifiable Orthogonal STBC. See publication [1] for more detail about the algorithm and [2] for more details about the identifiability conditions.
The zip file contains three m files.

- space_time_coding.m (perform space time coding)
- SOS_channel_estimation_OSTBC.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.
