Fast algorithm for beamforming problems in distributed communication of relay networks
A sequential quadratic programming (SQP) method is proposed to solve the distributed beamforming problem in multiple relay networks. The problem is formulated as the minimization ...

Distributed beamforming for OFDM-based cooperative relay networks under total and per-relay power constraints
This paper addresses the problem of beamforming (BF) design for orthogonal frequency division multiplexing (OFDM) based relay networks over frequency-selective channels. Both freq...

Distributed power allocation in multi-user multi-channel cellular relay networks
In this paper, we consider the amplify-and-forward relaying transmission in the downlink of a multi-channel cellular network with one base station and multiple relay-destination pa...

Outage-optimal transmission in multiuser-MIMO Kronecker channels
In this work, we look at single user and multiuser Multiple-Input Multiple-Output (MIMO) beamforming networks with Channel Distribution Information (CDI). CDI does not need to be ...

Joint Scheduling and Relay Selection in One- and Two-Way Relay Networks with Buffering
— In most wireless relay networks, the source and relay nodes transmit successively via fixed time division (FTD) and each relay forwards a packet immediately upon receiving. In...
