本文介绍了一种用于短码字的信道编码设计框架，该框架可以实现比以往方法更低的误码层。该编码是基于卷积编码与q元线性组合和不等能量分配相结合的。仿真结果表明，在很低的误码率(BER)下，所提出的系统将表现出比以前的方法更低的误码率平台，并且在中值误码率时有很小的性能损失。另一方面，当选择比以前的方法更高的误差下限时，中程BERS的性能损失可以忽略不计。
This letter introduces a channel coding design framework for short-length codewords which can achieve lower error floor than previous approaches. The proposed code is based on combining convolutional coding with a q-ary linear combination and unequal energy allocation. Simulation results suggest that for very low Bit Error Rates (BER) the proposed system will exhibit lower error floors than previous approaches, with a small performance penalty at mid-range BERs. On the other hand, when selecting an error floor higher than the previous approaches, the loss in performance at mid-range BERs is negligible.
