In the massive multiple-input and multiple-output (Massive MIMO) systems, the maximum likelihood (ML) detection problem is NP-hard and becoming classically intricate with the number of transmitting ...

Abstract: For the detection of phase shift keying (PSK) modulated signal in the presence of phase error and Gaussian noise, the maximum likelihood detection with self ...

Abstract: In this paper a maximum likelihood detection problem for a digital communication system is reformulated as a semidefinite programming (SDP) problem. A relaxation of this problem is done. An ...

STRL is developing a wireless millimeter-wave mobile camera that transmits low-delay, high-quality, low-compression Hi-Vision (HDTV) signals for program materials use. The use of multiple-input ...
