Abstract

In this paper we present a new approach to code block segmentation used on the 3GPP Standard LTE-Advanced channel coding physical layer. Code block segmentation is a generic procedure commonly applied before turbo encoding whose sole function is to fragment a large transport block into smaller code blocks, reducing memory requirements of the turbo code interleaver. The main result of this paper is a speedup of 80 times over the original procedure defined by the 3GPP Std. when implemented in a DSP architecture.
