| Abstract(in English) | In multiple-input multiple-output (MIMO) multiplexing, a superposition of data blocks transmitted from different transmit antennas using the same carrier frequency is received. In a frequency-selective channel, joint use of frequency-domain equalization (FDE) and signal detection of parallel transmitted signals is essential. Recently, we proposed an iterative frequency-domain interference cancelation (FDI^2C) using two dimensional minimum mean square error FDE (2D MMSE-FDE). Assuming ideal channel estimation, we showed that a good bit error rate (BER) performance is obtained. In this paper, we apply a cyclic delay pilot based channel estimation (CDP-CE) and evaluate by computer simulation the BER performance of multicode direct sequence code division multiple access (DS-CDMA) MIMO multiplexing with iterative FDI^2C and 2D MMSE-FDE. |
