Quantization and Bit Allocation for Channel State Feedback for Relay-Assisted Wireless Networks
Ehsan Karamad, Behrouz Khoshnevis, Raviraj Adve
This paper investigates quantization of channel state information (CSI) and bit allocation across wireless links in a multi-source, single-relay cooperative cellular network. Our g…
Optimal Shape-Gain Quantization for Multiuser MIMO Systems with Linear Precoding
Muhammad Nazmul Islam, Raviraj Adve, Behrouz Khoshnevis
This paper studies the optimal bit allocation for shape-gain vector quantization of wireless channels in multiuser (MU) multiple-input multiple-output (MIMO) downlink systems based…
Bit Allocation Laws for Multi-Antenna Channel Feedback Quantization: Multi-User Case
Behrouz Khoshnevis, Wei Yu
This paper addresses the optimal design of limited-feedback downlink multi-user spatial multiplexing systems. A multiple-antenna base-station is assumed to serve multiple single-an…
Bit Allocation Law for Multi-Antenna Channel Feedback Quantization: Single-User Case
Behrouz Khoshnevis, Wei Yu
This paper studies the design and optimization of a limited feedback single-user system with multiple-antenna transmitter and single-antenna receiver. The design problem is cast in…
Grassmannian Beamforming for MIMO Amplify-and-Forward Relaying
Behrouz Khoshnevis, Wei Yu, Raviraj Adve
In this paper, we derive the optimal transmitter/ receiver beamforming vectors and relay weighting matrix for the multiple-input multiple-output amplify-and-forward relay channel.…
