| 摘 要： | 对已有的传统译码算法如迫零算法（ZF）、最小均方（MMSE）算法、连续抵消（SIC）算法等的性能进行了研究,并在此基础上提出将迫零算法与连续抵消算法、最小均方算法与连续抵消算法相结合,构成迫零-连续抵消算法（ZF-SIC）与最小均方-连续抵消算法（MMSE-SIC）,从而明显改善系统的误码性能。此外,对收发两端采用不同天线数时的系统误码性能进行了仿真与分析,同时仿真分析了系统采用QPSK与16QAM调制方式的误码性能,最后给出仿真分析结果。

| Abstract: | The performance of traditional decoding algorithms,such as ZF algorithm,MMSE algorithm and SIC algorithm is studied.Based on this and by combining ZF with SIC and MMSE with SIC,respectively,the new algorithms of ZF-SIC and MMSE-SIC are thus formed,these new algorithms significantly improve the BER performance.In addition,the BER performance of the system with different transmitting and receiving antennas is simulated,including the BER performance of different modulations in the system,such as QPSK and 16QAM... |
