Block-based precoding for serially concatenated codes
Block-based precoding for serially concatenated codes
Precoders have been shown to facilitate iterative decoding convergence towards the Maximum Likelihood (ML) performance in serially concatenated schemes. In this letter, we propose a novel block-based precoder as an alternative to classic convolutional precoders. Furthermore, we demonstrate that the proposed block-based precoder facilitates operation at significantly reduced channel Signal to Noise Ratios (SNRs) in practical schemes, having limited latencies, as well as limited implementational and computational decoding complexities.

Abstract
Precoders have been shown to facilitate iterative decoding convergence towards the Maximum Likelihood (ML) performance in serially concatenated schemes. In this letter, we propose a novel block-based precoder as an alternative to classic convolutional precoders. Furthermore, we demonstrate that the proposed block-based precoder facilitates operation at significantly reduced channel Signal to Noise Ratios (SNRs) in practical schemes, having limited latencies, as well as limited implementational and computational decoding complexities.
