| Abstract(in English) | We have been developing an 800MHz-band MIMO-OFDM FPU system that can achieve a higher spectrum efficiency and more reliable mobile wireless transmission. To enhance the mobile transmission performance in an urban area including LOS environments, we propose an iterative LDPC-Coded MIMO system with long term interleaving. We previously showed by computer simulation that it could effectively improve the bit error rate performance. Following the computer simulation, some field experiments were conducted in an urban area, and the capability of the LDPC-Coded MIMO system which has a spatial interleaver in addition to time interleaver was determined. In this report, we show that the bit error rate performance has been significantly improved when both interleavers are used especially in high eigenvalue-ratio environments such as LOS environments. However, the performance improvement is less if only one of them is used. |
