摘要

传统的信源信道编码调制，都是基于四十年代香农分离理论的比特级和定长符号级解调译码，采用均匀分布和等概率的星座映射，在资源受限的无线通信系统中，难以与动态变化的多径信道相匹配，不可逾越通信技术发展所面对的可靠性墙和功耗墙等障碍.本文针对比特级和定长符号级调制/解调译码框架的局限，将变长信源信道编码与非等概率、优化的非均匀APSK(Amplitude Phase Shift Keying)调制星座映射相结合，提出了不等概率可变长符号联合信源信道编码的调制方法.仿真实验结果表明：该方法在10的-5次方量级的符号差错率下，同现存的符号级2D-8PSK方法比较，至少可获得约2.5dB的功率信噪比增益，同现存的比特级16APSK方法比较，至少可获得约1.1dB的功率信噪比增益.

Abstract

Conventional joint source-channel coded modulation is based on bit-level or fix-length symbol-level demodulation and decoding

derived from Shannon’s separation theory in 1940s. Uniform distribution and equiprobable constellation mapping are used

but they are not suitable for dynamic multipath channels. Meanwhile

the assumption of separation theory cannot be satisfied in source limited communication networks

and obstacles such as reliability and power consumption cannot be surmounted faced by the development of communication technology. The limitation of bit-level and fix-length symbol-level modulation/demodulation and decoding is paid attention. By combining variable-length joint source-channel coding with non-equiprobable and optimized unequal APSK(Amplitude Phase Shift Keying) modulation constellation mapping

a method of joint source-channel coding modulation for non-equiprobable variable-length symbols is proposed. The simulation experiments show that the proposed method obtains an SNR(Signal Noise Ratio) gain over 2.5dB compared to the existing symbol-level 2D-8PSK method

and an SNR（Signal Noise Ratio） gain over 1.1dB compared to existed bit-level 16APSK method

under the SER(Symbol Error Rate) of the order of -5 of 10.
