摘要

In millimeter-wave communications (MMWC), multipath components (MPCs) have different steering angles and independent fadings. Park and Pan recently proposed a simple scheme for both transmitter and receiver to concurrently beamform towards multiple steering angles of MPCs to achieve both array gain and diversity gain. However, when the number of MPCs is greater than that of the transmit or receive antennas, a solution of antenna weight vector (AWV) does not exist. To cope with this problem, two multipath grouping (MPG) schemes, namely MPG-steering vector grouping and MPG-channel vector grouping, are proposed. These schemes group the MPCs that have close steering angles, and define an equivalent MPC for each non-empty group in both the transmitter and receiver. As the number of non-empty groups is always no larger than that of antennas in both the transmitter and receiver, a solution of AWV is guaranteed. Moreover, performance comparisons show that the two proposed MPG schemes achieve not only full diversity, but also an even better array gain than that of the scheme proposed by Park and Pan.
