摘要

码短是实践中常用的译码方法，但其解析译码性能尚不清楚。在本文中，我们给出了在AWGN和Rayleigh衰落信道中工作的线性缩短和缩短-扩展块/积码的权重枚举器和误码率性能估计的严密表达式。这些表达式很容易使用，因为它们是根据原始(未缩短的)代码属性表示的，这些属性被广泛报道。并推导了与码短相关的渐近编码损失表达式

On the Weight Enumerator and BER Bounds of Shortened Block and Product Codes

Code shortening is commonly performed in practice but its analytical decoding performance is not well understood. In this paper, we present tight expressions for estimating the weight enumerator and hence BER (bit error rate) performance of linear shortened and shortened-extended block/product codes operating in AWGN and Rayleigh fading channels. The expressions are easy to use as they are expressed in terms of the original (un-shortened) code properties, which are widely reported. Asymptotic coding loss expressions associated with code shortening are also derived
