Abstract

With the tremendous development of mobile Internet and big data, much attention has been attracted on streaming data transmission. In this paper, we propose a quasi real-time transmission scheme using spatially coupled LDPC codes for forward error correction. Recursive encoder and sliding-window decoder with low-latency and low-complexity are employed for data transmission. When any error is reported, additional information is requested and retransmitted. Capacity-approaching performance can be achieved by constructing proper ensembles according to channel conditions. Theoretical thresh-olds and simulation results are provided, which illustrate the good performance.

Keywords: streaming data spatially coupled ldpc codes latency throughput
