摘要

介绍并分析了一种基于频率选择信道的正交频分复用(OFDM)信号检测算法。仿真结果表明，该检测策略通过标准的Viterbi算法实现，在不需要周期性传输训练块的情况下，在适度增加接收器复杂度的情况下，提供了优于差分检测的性能。

Blind channel equalization and data detection for OFDM transmissions on frequency-selective channels

A novel detection algorithm for orthogonal frequency division multiplexing (OFDM) signals transmitted over frequency-selective channels is introduced and analyzed. Simulation results show that the proposed detection strategy, implemented via a standard Viterbi algorithm, provides improved performance over differential detection with a moderate increase in receiver complexity, and without requiring the periodic transmission of a training block.
