Unrolled Polar Decoders, Part II: Fast List Decoders
Polar codes asymptotically achieve the symmetric capacity of memoryless channels, yet their error-correcting performance under successive-cancellation (SC) decoding for short and moderate length codes is worse than that of other modern codes such as low-density parity-check (LDPC) codes. Of the many methods to improve the error-correction performance of polar codes, list decoding yields the bes...
متن کاملA 237 Gbps Unrolled Hardware Polar Decoder
In this letter we present a new architecture for a polar decoder using a reduced complexity successive cancellation decoding algorithm. This novel fully-unrolled, deeply-pipelined architecture is capable of achieving a coded throughput of over 237 Gbps for a (1024,512) polar code implemented using an FPGA. This decoder is two orders of magnitude faster than state-of-the-art polar decoders.
متن کاملLow-complexity Multi-Bit Iterative Decoders: Algorithms and Hardware Architectures
We present a new type of iterative decoders for low-density parity check (LDPC) codes that use simple Boolean functions for variable node processing and surpass the belief propagation decoders in the error floor region. We discuss the error performance, guaranteed error correction capability and speed and implementation complexity of these decoders as factors crucial for application that requir...
متن کاملLow-Latency Software Polar Decoders
Polar codes are a new class of capacity-achieving error-correcting codes with low encoding and decoding complexity. Their low-complexity decoding algorithms rendering them attractive for use in software-defined radio applications where computational resources are limited. In this work, we present low-latency software polar decoders that exploit modern processor capabilities. We show how adaptin...
متن کاملImplementation of Polar Code Decoders
In this report, we review the construction of polar codes and we briefly present the main results that lead to the conclusion that polar codes are capacity achieving over binaryinput discrete memoryless channels. Moreover, we discuss a more sophisticated variant of successive cancellation decoding, namely list successive cancellation decoding, that aims to improve the finite-length performance ...
