Abstract

The main obstacle for the implementation of multiple-input multiple-output (MIMO) phased arrays is the large number of matched filters due to the waveform diversity provided. In this paper, we propose an array thinning technique targeted at MIMO phased arrays with a limited number of matched filters in each receiver. We formulate this thinning problem as a subproblem of joint Tx-Rx selection which chooses k transmitter-receiver (Tx-Rx) pairs from the available N pairs. We then show that the solution space of the new problem is highly overlapped with the global joint selection. Hence, the matched filter constrained (MFC) selection, which operates over a far smaller space achieves the solution with less computational effort.
