Block-based precoding for serially concatenated codes

Maunder, R. G. and Hanzo, L. (2009) Block-based precoding for serially concatenated codes IEEE Communications Letters, 13, (10), pp. 794-796.

Record type: Article


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.
