Abstract
We consider an iterative phase synchronization scheme based on maximum a posteriori probability algorithm. In classical approaches, the phase noise estimation model considers one sample per symbol at the channel and receiver. However, information theoretic studies suggested use of more than one sample per symbol at the channel and receiver for achieving higher performance. In this article, a soft-information aided iterative receiver is derived, which uses off-the-shelf blocks for detection and demodulation by keeping the complexity of the receiver acceptable. We consider here two samples per symbols at the channel and receiver in a pragmatic paradigm. It is shown that phase noise estimation can be significantly improved at the expense of modest processing overhead. Simulation results are presented for low-density parity check coded quadrature amplitude modulations. Our results show a significant performance improvement for strong phase noise values compared to classical receiver approaches.
摘要
本文考虑一种基于最大后验概率算法的迭代相位同步方案。 在经典方法中,相位噪声估计模型在信道和接收器的每个符号处考虑一个样本。 但是,信息理论研究建议在信道和接收器的每个符号上使用多个样本以实现更高的性能。 在本文中,得出了一种软信息辅助迭代接收器,该接收器使用现成的块进行检测和解调,以保持接收器的复杂性可接受。 在这里,我们以务实的范例考虑每个符号在信道和接收器处的两个样本。 结果表明,以适度的处理开销为代价,可以显著改善相位噪声估计。 给出了针对低密度奇偶校验编码的正交幅度调制的仿真结果。 结果表明,与传统的接收器方法相比,强相位噪声值具有显著的性能改善。
