Antenna arrays used in compressive sensing based DOA estimation algorithms are generated randomly to minimize mutual coherence. This scheme suffers from practical limitations. For an antenna array that is sufficiently random, some elements of the array would almost always fall very close to each other, which is not practicable. Rectangular arrays, although very uniform and practicable, suffer from...
In this paper we address the problem of two-way communication in multiple peer-to-peer relay networks, with perfectly known channel state information. Herein, multiple terminal transceiver nodes in the network are organized into two groups, and transceivers in each group want to simultaneously conduct bidirectional communications with their respective peers in the other group through the assistance...
Approximate formulations for the 3-dB beamwidth are derived in this letter to measure the spatial resolution of the broadband nonredundant array (NRA) and minimum redundancy array (MRA), which assume the ideal continuous-time, infinite-length filters with the frequency responses obtained by the linearly constrained minimum variance (LCMV) optimization. By these formulations, the beamwidths of NRA...
