UFMC-MIMO波束成形传输方案设计
Beamforming Transmission Scheme Design for UFMC-MIMO
摘要
Abstract
In order to adapt to demands in future wireless communication system including equipment diversity, high data rate, low latency and low power consumption, new waveform has become one of the keytechnologies studied in 5 G wireless communication system. Universal filtered multicarrier (UFMC) is a widely researched 5 G candidate waveform. However, the existing research only involves with UFMC-SISO scenario, and feasibility and performance of UFMC-MIMO remain vacant. Considering MIMO is a necessary scenario in 5 G, it has great significance to study UFMC-MIMO. A feasible UFMC-MIMO system scheme including the transmitter, the receiver and the precoding realizing algorithm is proposed. It is proved that this UFMC-MIMO scheme can recover transmitted data correctly by mathematical derivation and its performance is verified by simulation. Simulation results show that UFMC-MIMO outperforms OFDM-MIMO no matter in AWGN channel or multipath channel, and it has great advantage over robustness to relative carrier frequency offset, which validates that UFMC-MIMO transmission scheme has the capacity to be utilized in 5 G wireless communication system.关键词
