Interference-of-two-beams

在matlab环境下对ofdm进行仿真的程序(In matlab ofdm simulation under the environment of the procedure)

一个二阶水槽模型，包括两级水槽的输出曲线。(A second-order sink models, including two tanks of the output curve.)

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. Reference: [1] Ammar, N. Ding, Z.
