摘要: 針對(duì)V-BLAST信號(hào)通過(guò)分布的發(fā)射天線(xiàn)進(jìn)入信道，該文提出了一種由于發(fā)射天線(xiàn)地域上的分布性引起的各發(fā)射天線(xiàn)發(fā)射信號(hào)不同時(shí)到達(dá)接收天線(xiàn)的V-BLAST排序干擾抵消(Order Interference Cancellation, OIC)檢測(cè)算法。計(jì)算機(jī)仿真顯示，該算法適用于任意個(gè)數(shù)的接收天線(xiàn)，在較高信噪比(20dB)的條件下，性能優(yōu)于直接迫零算法3dB以上。在相同信噪比條件下，分布發(fā)射天線(xiàn)V-BLAST的排序干擾抵消檢測(cè)算法比集中發(fā)射天線(xiàn)V-BLAST的排序干擾抵消檢測(cè)算法有著更好的性能。Abstract: An Order-Interference-Cancellation (OIC) detection scheme is presented for Distributed Transmit Antennas Vertical Bell Labs Layered Space-Time (DTA-V-BLAST) systems. Some preliminary simulation results in single-path Rayleigh fading channel show that this algorithm can be used in the system with arbitrary receive antennas, the average bit error rate (BER) performance of this OIC approach is more 3dB better than using direct Zero-Frocing(ZF) scheme on the higher SNR (above 20dB). The capability of DTA-V-BLAST-OIC is better than the Golden scheme used in the V-BLAST signals with co-location transmit antennas with the same SNR.
