Industry communications systems without thread has grown tremendous over the last few years, these systems have evolved significantly in terms of services offered. Why the deployment of new communications systems(LANs, mobile radio systems, etc.) requiring transmit rates higher and higher in frequency bands is reduced more important but the traditional systems of transmission for the information which should be issued successively over time were put in competition with new approaches in which the information is transmitted simultaneously, but the speed of the processing time has always been a big problem of digital communication. The main objective of this work is to design an improvement for speed with a better precision in MIMO MC-CDMA broadband receiver for optimal data processing. This work proposes to focus on the design methodology and experimental implementation of a MIMO MC-CDMA receiver using DSP C64x+, we propose a new architecture of a MIMO MC-CDMA Receiver. The interest of this architecture is an enhancement that allows reducing the processing time data from a MIMO MC-CDMA receiver keeping better performance using the CORDIC operator and the fixed point to increase processing rates.
