Simulation d’un système de communication MISO avec le codage OFDM-CDMA

Abstract

As part of this research, we are interested in a communication system MISO (multiple input single output) coded OFDM-CDMA as well as telecommunications systems MIMO (multiple input multiple output) for spatial multiplexing and OFDM. The scope of this research work can also be stationary applications (eg. Wi-Fi, IEEE) and mobile applications (eg. LTE, 3GPP). The objective of this thesis is to study and improve the transmission and reception of technical systems MISO (Multiple Input Single Output) in a multi-carrier OFDM context (Orthogonal Frequency Division Multiplex. Furthermore, technical to improve the exploitation of frequency diversity and / or time is associated with OFDM, namely the CDMA technique in a schema type MC-CDMA (Multi Carrier-Code Division Multiplex Access) also called: OFDM-CDMA. We associated OFDM and space-time block coding in the frequency domain in the form of SFBC (Space Frequency Block Code) for different configurations of multi-antenna systems SISO, SIMO, MISO and MIMO. We offer the simulation of a MISO system using Multicarrier Modulation Delay Diversity (MDDM).
