Abstract

Iterative decoding has emerged as one of the most promising techniques for improving receivers performance. This paper is focused on exploring the feasibility of software implementation of iterative decoding algorithms for the 2nd and 3rd generations of the cellular communications standards. Two examples for iterative decoding algorithms are described: turbo decoding for the 3G cellular standards and turbo equalization for a GSM receiver. The principles described can be used to efficiently construct and implement other iterative decoding algorithms
