摘要

幅度相移键控(APSK)由于具有可观的整形增益而成为一种新兴的调制方案。本文研究了针对非等概率传输系统的不等APSK星座映射问题。提出了一种简化优化的非等概率符号传输的映射与解映射方法。仿真结果表明，该方法优于传统的星座和映射方法。

Optimized Unequal APSK Constellation Mapping and Demapping for Non-equiprobable Transmission Systems

Amplitude phase shift keying(APSK) is an emerging modulation scheme due to its considerable shaping gain. In this paper, unequal APSK constellation mapping aiming at non-equiprobable transmission system is concerned. A simplified and optimized mapping and demapping method for non-equiprobable symbols’ transmission is proposed. Simulation results show that the proposed mapping and demapping method outperforms conventional constellations and mappings.
