有频偏的OFDM信号的抗干扰迭代式接收机
An Iterative Receiver for OFDM Signal with Frequency Offset and Cochannel Interference
-
摘要: 针对受到共信道干扰的有频率偏移的OFDM信号，该文提出了一种接收机，其基本思想是先做干扰抑制，再做频偏估计。仿真实验证实了该文提出的接收机具有良好的性能。Abstract: In this paper, a receiver is proposed for the OFDM signal with CoChannel Interference (CCI) and frequency offset. The basic idea is to perform interference suppression before frequency offset estimate. Computer simulations verify the effectiveness of the proposed receiver.
