Performance analysis of OFCDM, MC-CDMA and OFDM for wire — Free

The multiple access technique is suggested for 4G communication system. The various types of multiple access technique are available in the communication system. In this broadsheet compare the enactment of the three most familiar methods constructed on the bit error rate. The three familiar techniques are orthogonal frequency division multiplexing (OFDM), Multi-Carrier Code Division Multiple Access (MC-CDMA) and orthogonal frequency and code division multiplexing (OFCDM) based on the MATLAB simulation results which method is suitable to execution for 4G communication system. The performances of the three methods are examined by the probability of bit error rate. Above three methods the OFCDM is suggested for 4G generation because the BER is low for given SNR then compare to OFDM and MC-CDMA.
