对于多发单收天线(MISO)通信系统，考虑发射端信道状态信息的差错(ECSI)。

For a multiple input single output (MISO) communications system, the presence of the erroneous channel state information (ECSI) must be taken into consideration.

本文研究了低回馈信道状态信息的自适应OFDM和SC - FDE系统，即利用有限的信道状态信息实现自适应传输。

This thesis focuses on adaptive OFDM and adaptive SC-FDE with low feedback channel state information (CSI), that is, how to carry out adaptive transmission by using limited CSI.

本文在已知信道状态信息的前提下，将MIMO和OFDM技术相结合，提出了一种新的MIMO - OFDM系统的功率分配和自适应调制方法。

In this paper, a novel power allocation and adaptive modulation method is proposed on the basis of the combination of MIMO and OFDM technology.
