Abstract
En 中文
Joint source channel decoding (JSCD) for variable length codes (VLCs) has been shown to be effective for error-prone channels. In this paper, we propose two schemes to enhance the performance of the existing bit-based JSCD approach for VLCs. Simulation results show that the performance of the decoder can be significantly improved, while the computational complexity is only slightly increased by using our proposed schemes.
