Performance analysis of data transmission in MC-CDMA radio interface with turbo codes

Abstract

Multi-carrier code division multiple access (MC-CDMA) technique is a combination of two radio access techniques: CDMA and orthogonal frequency division multiplexing and has the advantages of both techniques. The paper presents the design of transmitter and receiver for MC-CDMA radio interface. It also presents encoders and decoders of turbo codes which were used in simulation of the MC-CDMA technique. Two turbo codes with 8-state recursive systematic convolutional were used in the simulation. The simulation results of the transmission quality in additive white Gaussian noise (AWGN) channel presented in the paper show bit error rate and frame error rate performance of MC-CDMA technique with the turbo codes and allow for comparison the performance of both turbo codes.

“…The proposed method can be adopted in multi-carrier systems (MC-CDMA [14]). Moreover, the proposed solution can be implemented in systems using advanced frequency reuse methods, described in [15][16].…”
