Abstract:


The multi carrier technique looks promising as a 4G standard. Need of next generation is low power and high data rate, to increase data rate it is required to increase the bandwidth, at large bandwidth the channel becomes more frequency selective and more robust, channel model proposed by study group IEEE 802.15.SG3a is one of the example of high frequency UWB channel model. This paper evaluates the bit error rate (BER) performance of multi-carrier code division multiple access (MCCDMA) over high frequency multi-path channel model of study group IEEE 802.15.SG3a. We investigated the BER performance, with different modulation schemes like binary phase shift key (BPSK) and delta modulation (DM), over IEEE channel using different number of carrier in MCCDMA system and compare the performance with theoretical BER values over AWGN and Rayleigh channel.BER curve shows that MC-CDMA system can withstand in IEEE channel and DM is more suitable modulation scheme.
