AbstractMulticarrier Code Division Multiple Access (MC-CDMA) is attractive technique for high speed wireless data transmission; it's a combination of Orthogonal Frequency Division Multiplexing (OFDM) and Code Division Multiple Access (CDMA). OFDM employs a number of orthogonal subcarriers, this increases the symbol duration while the CDMA technique provides high capacity over other conventional multiple access schemes. In this paper discusses implementation of base band MC-CDMA system using the FPGA technique, all modules are designed using VHDL programming language. The electronic functional performance of designed circuits is tested by simulations using VHDL programming language on XILINX ISE 9.2i. The proposed model is designed using (Fast Fourier Transform/ Inverse Fast Fourier Transform) and the spreading code used is the gold code, the implementation of the proposed model using Spartan-3A/3AN, XC3S700N-3FGG484 FPGA of Xilinx family.
