一种LST-CPM系统的简化接收机

Abstract

Abstract:

Increasing attention is paid to Continuous Phase Modulation (CPM) system due to its characteristics of constant amplitude and high spectrum effectiveness in the field of wireless communication,so reducing the decoding complexity of the system is a key topic.In this paper,based on Layered Space Time (LST),a receiver of reduced complexity consisting of Laurent decomposition of CPM signals and MMSE detector is presented.In the low SNR condition,it achieves near-Maximum Likelihood (ML) performance with feasible complexity.Both theoretical derivation and simulated result confirm the effectiveness of the proposed method.

Key words: LST;CPM modulation;Laurent decomposition;MMSE detector
