Abstract

An extended SNR concept is proposed to evaluate the performance of hybrid ARQ with code combining. It is shown that the analysis of hybrid ARQ with code combining could be transformed into the analysis of FEC by using the proposed extended SNR. The extended SNR formula with respect to the code symbols in diversity combining is derived, which includes Pursley's SNR formula as a special case. An approximation is presented to evaluate hybrid ARQ with code combining. It is validated by simulation and numerical analysis that both the extended SNR analysis and the proposed approximation are applicable for the performance analysis of hybrid ARQ with code combining.

扩展信噪比及其在码组合混合ARQ系统性能分析中的应用

提出了一种扩展的信噪比概念来评价带有码合并的混合ARQ的性能。结果表明，利用所提出的扩展信噪比，可以将编码组合的混合ARQ分析转化为FEC分析。推导了分集组合中码号的扩展信噪比公式，其中以珀斯利信噪比公式为特例。提出了一种基于代码组合的混合ARQ估计方法。仿真和数值分析结果表明，扩展的信噪比分析方法和所提出的近似方法均适用于编码组合的混合ARQ性能分析。
