摘要
论文分析了OFDM系统中载波偏差引起的子载波干扰,设计了一种面向判决的载波跟踪环。仿真结果表明,环路在低信噪比时工作良好,接收机的误码率接近没有载波偏差时的性能。
In this paper, we analyze the intercarrier interference in OFDM system, A decision-directed Frequency Tracking Loop is described. The results of simulation show that the loop works well for a low SNR and the BER of the receiver closely approaches the performance of the reception without a frequency offset.
