摘要： Modern communication systems must cope with varying channel conditions and differing throughput constraints. Polar codes despite being the first error-correcting codes with an explicit construction to achieve the symmetric capacity of memoryless channels are not currently employed against other older coding protocols such as low-density parity check (LDPC) codes as their performance at short/moderate lengths has been inferior and their decoding algorithm is serial leading to low decoding throughput. Accordingly techniques to address these issues are identified and disclosed including decoders that decode constituent codes without recursion and/or recognize classes of constituent directly decodable codes thereby increasing the decoder throughput. Flexible encoders and decoders supporting polar codes of any length up to a design maximum allow adaptive polar code systems responsive to communication link characteristics, performance, etc. whilst maximizing throughput. Further, designers are provided flexibility in implementing either hardware or software implementations.
摘要翻译：现代通信系统必须应对不同的信道条件和不同的吞吐量限制。尽管作为具有实现无记忆信道的对称能力的明确结构的第一纠错码目前并不适用于诸如低密度奇偶校验（LDPC）码之类的其他旧的编码协议，但是它们在短/中等长度下的性能一直较差，其解码算法串行导致低解码吞吐量。因此，识别和公开了解决这些问题的技术，包括解码组件代码而不递归和/或识别分组直接可解码的解码器，从而增加解码器吞吐量。灵活的编码器和解码器支持任何长度达到设计最大值的极性码，允许响应于通信链路特性，性能等的自适应极性码系统，同时最大化吞吐量。此外，设计人员在实现硬件或软件实现方面提供了灵活性。

摘要： There is described a multi-mode unrolled decoder. The decoder comprises a master code input configured to receive a polar encoded master code of length N carrying k information bits and N−k frozen bits, decoding resources comprising processing elements and memory elements connected in an unrolled architecture and defining an operation path between the master code input and an output, for decoding a polar encoded code word, at least one constituent code input configured to receive a polar encoded constituent code of length N/p carrying j information bits and N/p−j frozen bits, where p is a power of 2, and at least one input multiplexer provided in the operation path to selectively transmit N/p bits of one of the master code and the constituent code to a subset of the decoding resources.

摘要： Methods and systems for encoding data are described herein. The method comprises inputting data to a first pipeline of a non-systematic polar encoder capable of encoding a polar code of length nmax, extracting, via at least one first multiplexer of size log nmax×1, a first polar code of length n
