Les turbo-codes dans un contexte OFDM

Abstract

Orthogonal frequency division multiplexing (OFDM) has been successfully applied to a wide variety of digital communication applications in recent years. OFDM is a suitable candidate for high data rate transmission with Forward error correction (FEC) methods on wireless channels. Frequency-selective and time-selective channels are the most di cult to be treated. The use of a mutli-carrier technique such as OFDM and a channel coding such as turbo
