... ρ r is the scaling factor at Relay r. When there is no instantaneous CSI available at the relays, but statistical CSI is known, a useful constraint is to ensure that a given average transmitted ... (STC) has received a lot of attention in the last years as a way to increase the data rate and/or reduce the transmitted power necessary to achieve a target bit er ror rate (BER)...

... for Sparse Mimo Aperture Radar Consider a monostatic sparse MIMO aperture radar system with M separated subarrays. Each subarray is a standard uniform linear array (ULA) with N elements. Let a sub (θ) be ... equivalent to the two- way BP of the conventional phased array. There are two differences between a MIMO radar array and a conventional phased array. First, the orthogonal wave...
