摘　　要：Two variable channel-coding schemes with unequal error protection （UEP） are proposed in terms of speech transmission over VHF-mobile radio system. These channel coding are separately based on rate-compatible punctured convolution （RCPC） code scheme and rate-compatible punctured turbo （RCPT） code scheme. With optimum puncturing designation and suitable scheme of rate matching, these two UEP schemes can achieve intra-class unequal error protection, which makes the protection for source bits with different importance more accurate. Its real time implementation based on a TMS320C6416 digital signal processor is also presented. The experimental results suggest that this method have reasonable system complexity and short processing delay.Two variable channel-coding schemes with unequal error protection （UEP） are proposed in terms of speech transmission over VHF-mobile radio system.
