摘要
收发多天线系统(MTMRA)是未来无线通信系统的关键技术之一,它利用多个收发天线,大大提高了无线通信系统的容量,为实现高速、高质量的数据传输提供了可能。MTMRA系统将信道视为若干并行的子信道,在不需要额外带宽的情况下实现近距离的频谱资源重复利用,理论上可以极大地扩张频带的利用率,提高无线传输速率。
As a key technology of future communication systems, Multi-Transmit Multi-Receive Antennas （MTMRA） systems can greatly increase the capacity of the communication systems and make it possible to transmit the data in high speed and with high quality. MTMRA regards the channel as several parallel sub-channels, and implements reuses of the spectrum without any loss in bandwidth and transmit power. It has been demonstrated that MTMRA can greatly increase the frequency efficiency and transmission rate in theory.
