Abstract
In this letter, we propose a low-complexity hybrid precoding and combining design for the mmWave MUMIMO transmission, applicable to both fully-connected and subconnected structures. Analog precoding and combining schemes are firstly designed, where a joint approach, a decoupled approach, and a sub-optimal approach are proposed to harvest the array gain. Virtual path selection is performed to maximize the channel gain of the analog effective channel. Then, based on the effective channel, a low-dimensional zero-forcing (ZF) precoding is applied in the baseband to manage the interference. The simulation results show that the proposed techniques offer an enhanced performance-complexity trade-off compared to both existing hybrid schemes and fully digital schemes.
