Dalam saluran yang mengubah masa, maklumat keadaan saluran yang tersedia pada pemancar (CSIT) adalah lapuk disebabkan kelewatan masa yang wujud antara anggaran saluran pautan atas dan penghantaran data pautan bawah dalam sistem TDD. Dalam surat ini, kami mencadangkan kaedah prapengekodan berulang dan kaedah penyahkodan linear yang kedua-duanya berdasarkan kriteria ralat min kuasa dua minimum (MMSE) untuk mengurangkan gangguan antara aliran data dan pengguna yang dicipta oleh CSIT yang lapuk untuk sistem pautan bawah MIMO berbilang pengguna. Keputusan analisis dan simulasi menunjukkan bahawa kaedah yang dicadangkan boleh mengurangkan kemerosotan nilai CSIT yang sudah lapuk dan meningkatkan kapasiti sistem.

Abstract: In time-varying channels, the channel state information available at the transmitter (CSIT) is outdated due to inherent time delay between the uplink channel estimation and the downlink data transmission in TDD systems. In this letter, we propose an iterative precoding method and a linear decoding method which are both based on minimum mean-squared error (MMSE) criteria to mitigate the interference among data streams and users created by outdated CSIT for multiuser MIMO downlink systems. Analysis and simulation results show that the proposed method can effectively reduce the impairment of the outdated CSIT and improve the system capacity.
