A Review of Sub-Carrier Selection Techniques Employed in MC-CDMA System for 4G Networks
The Multi-Carrier Code Division Multiple Access (MC-CDMA) is becoming a very attractive multiple access technique for high-rate data transmission in the future wireless communication systems. This paper is focused on reviewing different sub-carrier selection techniques for MC-CDMA system. It has been seen that appropriate subcarrier selection technique can significantly improve Bit Error Rate (BER) performance, throughput performance, system capacity, speed and it results in higher spectrum efficiency as well as reduced power consumption at mobile terminal.
