Abstract― This paper describes a realistic capacity comparison of MIMO-CDMA and MIMO-OFDM schemes, by taking account of several practical factors, such as actual modulation and channel coding, channel estimation error, spectrum loss due to band-pass filter, and power loss due to pilot and control signal insertion. In the comparison, we employ the system parameters discussed in the 3rd Generation Partnership Project (3GPP). We also introduce a pilot and control cancellation scheme for practical consideration in MIMOCDMA. Computer simulation results clarify that MIMO-OFDM achieves higher capacity in high SNR region ……
