JSCC Based on JPEG2000 and WIPC- LDPC
基于JPEG2000和WIPCLDPC的联合信源信道编码

Utilizing the characteristic of JPEG2000 code stream format,a joint source channel coding(JSCC) scheme was proposed in this paper.A novel irregular LDPC with weight-increasing parity-check(WIPC) matrix(WIPC-LDPC) was first put forward,which can simply realize unequal error protection(UEP) characteristic.Then the different significant JPEG2000 code streams were coded by weight-increasing parity-check(WIPC) irregular LDPC with dissimilar degree bit nodes to realize UEP scheme.Simulation results show that the proposed JSCC can realize robust image transmission and outperforms other JSCC schemes proposed before.
