Convolutional/Single Parity Check Turbo Codes for Wireless Multimedia Communications

Abstract

Error correction codes are widely used in digital communications to improve the Quality of Service. The Quality of Service is typically expressed in terms of maximum acceptable frame error rate and bit error rate. The key implementation issues for most powerful error correction codes are the complexity and overall encoding/decoding latency. In this paper, short-frame turbo product codes for real-time wireless multimedia communications are proposed. Performance of the proposed turbo codes is studied through simulations on an additive white Gaussian noise (AWGN) channel. The obtained results indicate that the performance of these codes is quite exceptional given their decoding complexity.
