【简　介】: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 by about 1.2 (bps/Hz),
2.5 (bps/Hz), and 5.0 (bps/Hz) for average SNR values of 15 (dB), 20
(dB), and 30 (dB), respectively. The effectiveness of the pilot and
control cancellation scheme is also confirmed by a computer
simulation.
