单用户毫米波大规模MIMO系统的混合预编码方案设计
Design of a hybrid precoding scheme for single-user milimeter wave massive MIMO systems
摘要
Abstract
The digital precoding tactics for MIMO communication systems were deeply analyzed, and it was pointed that the traditional full digital precoding scheme for single-user millimeter wave massive MIMO systems can cause a system's high cost and high power consumption because it needs a large number of radio frequency (RF) chains.To solve the problem, a hybrid precoding scheme hybrid precoder at the transmitter and using the hybrid combiner at the receiver was proposed.The proposed scheme uses the iterative algorithm to design the analog precoding matrix first, and designs the digital precoding matrix according to the equivalent channel matrix generated by the interaction of the channel matrix and the analog precoding matrix.Then, it designs the hybrid combiner according to the hybrid precoder to maximize the spectral efficiency.The simulation comparison of the proposed scheme with the traditional full digital precoding scheme and the existing hybrid precoding scheme showed that the proposed scheme reduced the system's cost and energy consumption, furthermore, its performance outperformed the existing hybrid precoding scheme, and was very close to the traditional full digital precoding scheme.关键词
