Gateway Switching in Q/V Band Satellite Feeder Links
TL;DR: A modified switch and stay combining scheme is proposed for a Q/V band feeder link, but its performance is also evaluated over an end-to-end satellite link, which has close to optimal performance with notably lower complexity.
Journal ArticleDOI
Hybrid Transceivers Design for Large-Scale Antenna Arrays Using Majorization-Minimization Algorithms
Aakash Arora,Christos G. Tsinos,Bhavani Shankar Mysore Rama Rao,Symeon Chatzinotas,Bjorn Ottersten +4 more
TL;DR: This paper considers the hybrid precoder design as a constant modulus constrained matrix factorization (CMCMF) problem for the most common types of hybrid architectures namely, the fully and the partially connected ones and proposes two lines of algorithms based on the majorization-minimization (MM) and the minorization-maximization framework.
Proceedings ArticleDOI
Detection of sparse random signals using compressive measurements
TL;DR: A subspace model for the sparse signal where the signal parameters are drawn according to Gaussian law is used and the detector based on Neyman-Pearson criterion is obtained and analyzed to determine its operating characteristics when the signal covariance is known.
Journal ArticleDOI
An Asymptotically Efficient Weighted Least Squares Estimator for Co-Array-Based DoA Estimation
TL;DR: This work introduces a novel estimator for the co-array-based Direction of Arrival estimation employing the Weighted Least Squares (WLS) method, and implies that the proposed WLS estimator has a significantly better performance compared to existing methods.
Proceedings ArticleDOI
Large scale transmit diversity in Q/V band feeder link with multiple gateways
TL;DR: A practical switching strategy in a scenario with N+P GWs (N active and P redundant GWs) towards achieving GW transmit diversity and the interplay between the number of redundant and active GWs on the availability is illustrated.
