Narrow beamforming solutions for millimeter wave cellular networks require mobile and base stations to exhaustively search all angular space. This scanning is mandatory in order to detect the unique optimum beamforming and combining vectors prior to control and data signaling. However exhaustive search yields large computational complexity and increases beam discovery time and control plane latency...
This paper presents a distributed beamforming algorithm with a reduced computational complexity for a wireless relay network, where a source-destination pair is assisted by cooperating amplify-and-forward (AF) relays but suffers from additional interference. The relay weights are obtained by maximizing the signal-to-interference-plus-noise ratio (SINR) at the destination subject to individual relay...
MISO-OFDM systems enable the allocation of resources in the frequency and spatial domain to increase the data throughput of wireless systems. In this paper, we initially present a near-optimal solution to the MISO-OFDM Resource Allocation (RA) problem. This solution performs an exhaustive search over all possible user sets and then uses a dual-based approach to optimally assign power to the selected...
