Abstract :
Aiming at the problem of the asynchronous receiving for distributed antenna multiple-input multiple-output system (D-MIMO), a serial detection scheme based on matrix partition is proposed. Firstly, a smaller matrix is partitioned from the equivalent channel matrix and then signal is detected. Secondly, the detected signal in the first step of is used for interference cancellation, and the remainders are used for combination. And then another small matrix is partitioned from the channel matrix cancelled the interference and signal is again detected. This process is repeated until all the signals have been detected. Compared to the exiting Distributed Antenna Ordering successive interference cancellation (DA-OSIC) algorithm, computer simulation results show that the proposed detection scheme support the successive transmission of signals under the single-path Rayleigh fading channel. Meanwhile, as the length of signal sequence being large, the proposed algorithm has the same performance as the DA-OSIC scheme and has lower computational complexity.
