Abstract
We investigate transmission strategies for multiple antenna systems with partial spatial information of channel avail- able at the transmitter. A new beamforming method is proposed in which the beamforming matrix is determined from the partial spa- tial information in a novel but predefined way; as a result, the re- ceiver also knows the beamforming matrix. With this beamform- ing scheme, we develop a multiple antenna system concept that enables better use of the multiple-input multiple-output (MIMO) channels from a channel capacity perspective. The results show that the proposed methods lead to systems wherein the amount of channel feedback information can be significantly reduced with a minor sacrifice of achievable transmission rate.Keywords
