A minimum approximate-BER beamforming approach for PSK modulated wireless systems

, 2008
A beamforming algorithm is introduced based on the general objective function that approximates the bit error rate for the wireless systems with binary phase shift keying and quadrature phase shift keying modulation schemes.

Sonar beamforming based upon monaural localisation techniques [PDF]

, 1987
Includes bibliographies.Sonar beamforming is usually accomplished using a multi-element transducer array. To obtain high resolution, such a system is costly and complex. In contrast, many mammals are capable of good angular resolution using only a single

Multiuser hybrid analog/digital beamforming for relatively large-scale antenna arrays

, 2013
Power consumption and costs of the analog front-end (AFE) chains are often not negligible for large-scale antenna array systems. A low-complexity hardware architecture is to use a number of AFE chains that is less than the number of the antennas ...

Full-Duplex in Massive Multiple-Input Multiple-Output

IEEE Open Journal of Vehicular Technology
In-band full-duplex (FD) operation can double the spectral efficiency of massive multiple-input multiple-output (mMIMO) systems by allowing simultaneous transmission and reception over the same time/frequency slot. However, the main challenge encountered
