Abstract
This paper presents a 2D -ary Sliding-Window Belief Propagation (2DQSWBP) algorithm to decode Low-density Parity-check (LDPC) code which is utilized to compress highway traffic surveillance video under Wyner-Ziv video framework. This framework is beneficial for camera device with limited memory and computing ability. The differences of successive frames is modeled as Truncated Discrete Laplace (TDL) distribution. The experimental result shows the 2DQSWBP outperforms the -ary Belief Propagation (QBP) algorithm in both Bit-Error-Rate and computing time.
