摘要
文中介绍了基于DAPSK调制的OFDM系统,并用一种次最佳的软解调算法替代了复杂的、基于最大似然估计的最佳算法。仿真结果表明,该算法与OFDM系统可以很好的结合在一起达到复杂度和性能的折中。
The paper introduces the OFDM system based on differential amplitude and phase-shift keying （DAPSK） modulation and with a suboptimal soft defferential detection in place of the more complex maximum-likelihood （ML）-based differential detection. The simulation results show that the OFDM system based on this algorithm can achieve the best trade-off between performance and computation complexity.
