Abstract:

Aiming at the problem of the asynchronous receiving for distributed antenna multiple input multiple output systems, a serial detection scheme based on matrix partition is proposed. Firstly, a smaller matrix is partitioned from the equivalent channel matrix, from which, signals are detected. Then the first of the detected signals is used for interference cancellation, and the remainder is used for combination. Finally, another small matrixis partitioned from the channel matrix cancelled the interference. This process is repeated until all the signals are detected. Some computer simulation results under the single-path Rayleigh fading channel show that the proposed detection scheme supports the successive transmission of signal compared with the exiting distributed antenna ordering successive interference cancellation (DA-OSIC) algorithm. Meanwhile, as the length of signal sequence being large, the proposed algorithm has the same performance as the DA-OSIC scheme and has lower complexity.
