Towards Gaussian capacity, universality and short block length
Chulong Liang, Junjie Ma, Li Ping · 2016
Forward error control (FEC) codes based on turbo, low-density parity-check (LDPC) and polar principles provide practical approaches towards channel capacity. There are, however, remaining challenges. Some of these are listed below. · How to achieve performance with Gaussian signaling'? · How to design codes that are universally good over different channel conditions'? · How to reduce code length while maintain good performance? In this paper, we introduce a scheme based on the recent progresses on spatial coupling and compressed sensing. The new scheme offers a potential solution to the above mentioned challenges.
