As microwave spectrum becomes increasingly scarce, millimeter wave communication has gained wide attention for its sufficient bandwidth, which is also considered as one of the key technologies in the Fifth Generation (5G) communication networks. Different from microwave, millimeter communication is easy to suffer from the blockages. In order to take advantage of the wide spectrum and avoid the big...
This paper considers a multi-pair two-way relaying network, where multiple pairs of full-duplex users are served via a full-duplex relay with large-scale antennas under the amplify-and-forward protocol. Based on maximum-ratio combining/maximum-ratio transmission (MRC/MRT) processing, an exact achievable rate expression is derived by utilizing the statistical distribution of the channels to detect...
We propose an optimal minimum sidelobe modal beamforming approach based on the spherical harmonics decomposition for spherical sensor arrays, which provide the ability of three-dimensional broad-band beampattern synthesis. The spherical harmonics domain array processing problem is expressed with a matrix formulation. The weight vector design problem is written as a multiply constrained problem, so...
