Interpolation Based Transmit Beamforming for MIMO-OFDM with Partial Feedback
Transmit beamforming with receive combining is a simple method for exploiting the significant diversity provided by multiple-input multiple-output (MIMO) systems, and the use of orthogonal frequency division multiplexing (OFDM) enables low complexity implementation of this scheme over frequency selective MIMO channels. Optimal beamforming requires channel state information in the form of the be...
متن کاملBeamforming for OFDM based Hybrid Terrestrial-Satellite Mobile System
The thesis research concerns an integrated framework of terrestrial and satellite networks based on Orthogonal Frequency Division Multiple Access (OFDM) air interface which we call Hybrid Terrestrial-Satellite Mobile System (HTSMS). HTSMS which enables frequency reuse amongst the two networks serves users in urban areas via terrestrial Base Stations whilst satellite links provide service in rur...
متن کاملAdaptive Beamforming for OFDM Based Hybrid Mobile Satellite System
Global connectivity cannot be guaranteed by terrestrial networks due to the lack of infrastructure in rural areas. Neither can satellite networks assure this due to lack of signal penetration and capacity coverage issues in densely populated areas. To bridge this gap, we propose an Orthogonal Frequency Domain (OFDM) based hybrid architecture where users are provided service by existing mobile n...
متن کاملBayesian Optimal Data Detector for Hybrid mmWave MIMO-OFDM Systems with Low-Resolution ADCs
Hybrid analog-digital precoding architectures and low-resolution analog-to-digital converter (ADC) receivers are two solutions to reduce hardware cost and power consumption for millimeter wave (mmWave) multiple-input multiple-output (MIMO) communication systems with large antenna arrays. In this study, we consider a mmWave MIMO-OFDM receiver with a generalized hybrid architecture in which a sma...
متن کاملRobust Beamforming for Ofdm Modulated Two-way Mimo Relay Network
Robust Beamforming for OFDM Modulated Two-Way MIMO Relay Network. (May 2012) Jianwei Zhou, B.S., University of Hawaii at Manoa Chair of Advisory Committee: Shuguang Cui This thesis studies a two-way relay network (TWRN), which consists of two single antenna source nodes and a multi-antenna relay node. The source nodes exchange information via the assistance of the relay node in the middle. The ...
