MMSE-BLE Algorithm of Single-Carrier Multi-User Channel Capacity
A kind of minimum mean square error linear equalizer (MMSE-BLE) algorithm is presented for the solution on channel capacity of single-carrier code division multiple accesses (SC-CDMA) system, this algorithm received data symbol vector multiplied by covariance matrix by using Wiener estimator, and gets the decorrelation of multiple access interference (MAI), inter-symbol interference (ISI) and noise. MMSE-BLE algorithm calculates the channel capacity with MMSE criterion algorithm, so that it can analyze the multi-user uplink channel capacity of space-time coding SC-CDMA system under the multipath conditions effectively. The simulation results show that the number of user, path, transmitting and receiving antennas, multipath diversity gain, etc. All of them have an impact on the capacity of multi-user system, it seems that multiple antennas should be used for reception to get single-path diversity gain in frequency selective channels.
