A new design method of source-channel coding based on information and communication technology

With the fast development of the modern information and communication technology, there happens some profound transformation in the modern society, and information transfer method change quickly. A new design method for source-channel coding based on compressed sensing (CS) and low-density parity-check(LDPC) codes is proposed in the paper, which can achieve excellent performance by utilizing CS redundant information to correct LDPC decoding algorithm. Simulations show that performance of the proposed algorithm in reducing the bit-error rate is much better than that of LDPC codes.
