Abstract
The asymptotic spectral efficiency of multicarrier CDMA (MC-CDMA) with multiple transmit and receive antennas is analysed in this paper. The closed-form spectral efficiency is derived when matched filter and minimum mean square error (MMSE) front ends are employed. We consider the effect of the number of transmit and receive antennas on the performance of spectral efficiency. The spectral efficiency can be improved by choosing an appropriate loading factor and number of antennas in the transmitter and receiver. We also compare the spectral efficiency of MC-CDMA with that of SC-CDMA (single-carrier CDMA).
