The time–space receive transformation (TSRT) is proposed to increased the achievable rate of the time–space multiple-input-multiple-output (MIMO) system (where the signals received at different time instants and spatial spots are jointly processed) with faster-than-Nyquist (FTN) signaling (where the symbol rate is higher than the Nyquist rate) in the frequency-selective fading channel. It is shown that for the TSRT base MIMO system with FTN signaling, the interference from other blocks can be ineffective so that its achievable rate increases with the ratio of the symbol rate to the Nyquist rate and can reach the maximal information rate of the time–space MIMO system. It is also shown that with FTN signaling, the achievable rate of the TSRT base MIMO system is larger than that of the trailing-zeros based MIMO system and the OFDM based MIMO system, and the ratio of the symbol rate to the Nyquist rate increases this advantage.

提出了时空接收变换（TSRT），以更快的速度提高时空多输入多输出（MIMO）系统（在不同时刻和空间点处接收到的信号被共同处理）的可实现速率选频衰落信道中的非奈奎斯特（FTN）信令（符号率高于奈奎斯特率）。结果表明，对于带有FTN信令的基于TSRT的MIMO系统，来自其他块的干扰可能无效，因此其可达到的速率会随着符号率与奈奎斯特速率的比值的增加而增加，并且可以达到该时间的最大信息速率。空间MIMO系统。还表明，利用FTN信令，基于TSRT的MIMO系统的可实现速率大于基于尾随零的MIMO系统和基于OFDM的MIMO系统的可实现速率，
