Figure 2From: Throughput analysis of transmit-nulling SDMA with limited feedbackTransmit gain. (a) A column-reduced DFT matrix E 1 ( 3 ) and its column vectors e1,1, e1,2, and (b) the desired precoding matrix N1(30°) and its column vectors n1,1, n1,2. We assume the number of precoding matrices G=2, the number of transmit antennas N=3, and λ d =0.5.Back to article page
