Performance analysis of Binary FSK signals with L-Fold diversity selection combining techniques in a Nakagami-M fading channel
… Frequency Shift Keying (BFSK) receiver using Selection Combining techniques over a frequency non-selective, slowly fading Nakagami channel. These techniques are independent of the number of diversity branches, so simpler receivers can be employed. First order selection Combining (SC), second …

New Results on Selection Diversity over Fading Channels
… bit error rate performance of five different selection diversity combining schemes over slow, frequency non-selective Rayleigh, Nakagami-m and Ricean fading channels. Aside from the classical selection diversity, generalized selection combining and the "maximum output" selection methods, two …

Differential modulation and non-coherent detection in wireless relay networks
… of this relay topology using a linear combining method and two-symbol differential detection is examined in time-varying Rayleigh fading channels. New combining weights are proposed and shown to improve the system performance in fast-fading channels. The performance of the simpler …

Analysis of Advanced Diversity Receivers for Fading Channels
… study for a class of hybrid generalized selection combining technique for ultra-wideband, spread-spectrum and millimeter-wave communication receiver designs. The thesis also develops an exact mathematical framework to analyze the performance of a dual-diversity equal gain combining (EGC) …

Smart Base Station Antenna Performance for Several Scenarios - an Experimental and Modeling Investigation
… of the three base station diversity methods with selection combining (SC), maximal ratio combining (MRC), and equal gain combining (EGC) techniques for both urban and suburban non-line-of-sight (NLOS) environments are presented and summarized using the measured data. Forward-link performance of a …

Smart Antennas at Handsets for the 3G Wideband CDMA Systems and Adaptive Low-Power Rake Combining Schemes
… smart antenna system with diversity and adaptive combining schemes and propose a new combining scheme called hybrid combining. The proposed hybrid combiner combines diversity combiner and adaptive combiner outputs using maximal ratio combining (MRC). Since these diversity combining and adaptive …

Three fundamental pillars of decision-centered teamwork
… in three fundamental challenges: (i) Agent Selection, which consists of selecting a set of agents from an exponential universe of possible teams; (ii) Aggregation of Opinions, which consists of designing methods to aggregate the opinions of different agents into taking joint team decisions; …

Time Diversity Modelling and Implementation for Broadcast Satellite Systems at V-band
… (10s, 30s, 60s, and 180s) using two diversity combining methods, namely the selection combining (SC) and maximal ratio combining (MRC). The MRC method provided the best joint overall carrier to noise ratio.Finally, a near real-time implementation of TD at V-band was simulated, to demonstrate …

Doppler spread estimation in mobile fading channels
… of mobile speed estimation using diversity combining is investigated. Then, a nonparametric estimation technique is proposed that is robust to different channel variations. Finally, cyclostationarity-based speed estimators which can be applied either blindly or with the aid of pilot data, …
