چکیده

Multi-Carrier Code Division Multiple Access (MC-CDMA) system performance is evaluated with Convolutional error control coding in this paper. Multiple antennas are used at transmitting and receiving side to improve the performance. Various types of equalization schemes are examined. 2x2 antennas considered and code rate of convolutional encoder is 1⁄2. AWGN and Rayleigh fading channel is considered for simulation. The system is implemented with different types of receivers. Viterbi decoding is performed to retrieve the data. And simulation results show that error control coding provides better performance.
