Performance analysis of coding using Distributed Turbo Codes

Nowadays the need for fast and reliable communication is increasing, which leads us to look for new ways to enhance channel coding. In this paper, we will study the case of a distributed coding between two users that aim to transmit data to a common destination, where each user transmits a partial redundancy to the destination, and relies on the second user for the remaining. The purpose of distributing the redundancy creation and transmission, is to benefit from each user channel quality for a more accurate decoding. In the context of our analysis, we will use a 1/2 rate convolutional code with between users and a distributed Turbo code for transmission to the destination. However, this study will aim to highlight the different key factors, as well as the advantage of choosing a distributed encoding.
