This paper presents a novel IEEE 802.16e (WiMAX) based decoder that performs close to the 5G code but without the expensive hardware re-development cost. The design uses an extension of the existing WiMAX parity check code to reduce the initial decoding latency and power consumption while keeping the decoder throughput at maximum. It achieves similar Frame Error Rate (FER) compared to 5G (0.1 dB off), and most notably the error curves trend down like 5G instead flooring. At FER= 10⁻³ there is 0.1 dB gain in the FER code performance compared to WiMAX. An implementation of the design is a modified version of the existing fully-parallel WiMAX decoder that supports multi-rate codeword size and reduces the initial latency by 33%. Additionally, for SNR greater than 3 dB, decoding only the shorter code reduces the power consumption by 34%.

本文提出了一种新颖的基于IEEE 802.16e（WiMAX）的解码器，该解码器的性能接近5G代码，但没有昂贵的硬件重新开发成本。该设计使用了现有WiMAX奇偶校验码的扩展，以减少初始解码延迟和功耗，同时将解码器吞吐量保持在最大水平。与5G（关闭0.1 dB）相比，它实现了相似的帧错误率（FER），并且最明显的是，错误曲线像5G一样下降，而趋于下降。在FER = 10 ^-3与WiMAX相比，FER码性能提高了0.1 dB。该设计的实现是现有全并行WiMAX解码器的修改版本，该解码器支持多速率码字大小，并将初始延迟降低了33％。此外，对于大于3 dB的SNR，仅解码较短的代码可将功耗降低34％。
