摘要

研究正交频分复用(OFDM)系统中的联合均衡和窄带干扰抑制问题。由于传统的零强迫(ZF)接收器不能保证在严重干扰环境中具有令人满意的干扰抑制能力,因此我们研究了最小均方误差(MMSE)接收器的潜力,特别是通过利用OFDM信号的循环前缀中包含的冗余来评估其优势。

Joint equalization and interference suppression in OFDM systems
We consider the problem of joint equalization and narrowband interference (NBI) suppression in orthogonal frequency-division multiplexing (OFDM) systems. Since the conventional zero-forcing (ZF) receiver does not assure satisfactory interference suppression capabilities in severe interference environments, we investigate the potential of the minimum mean-square-error (MMSE) receiver, evaluating in particular the advantage that can be achieved by exploiting the redundancy contained in the cyclic prefix of the OFDM signal.
