Adaptive Orthonormal Random Beamforming and Multi-Beam Selection for Cellular Systems
SUMMARY Channel state information (CSI) at transmitter plays an important role for multiuser MIMO broadcast channels, but full CSI at transmitter is not available for many practical systems. Previous work has proposed orthonormal random beam-forming (ORBF) [16] for MIMO broadcast channels with partial channel state information (CSI) feedback, and shown that ORBF achieves the optimal sum-rate ca...
متن کاملNon-Orthogonal Random Access in MIMO Cognitive Radio Networks: Beamforming, Power Allocation, and Opportunistic Transmission
We study secondary random access in multi-input multi-output cognitive radio networks, where a slotted ALOHA-type protocol and successive interference cancellation are used. We first introduce three types of transmit beamforming performed by secondary users, where multiple antennas are used to suppress the interference at the primary base station and/or to increase the received signal power at ...
متن کاملCooperative Orthogonal Matching Pursuit strategies for sparse approximation by partitioning
Cooperative Orthogonal Matching Pursuit strategies are considered for approximating a signal partition, subjected to a global constraint on sparsity. The approach is designed to produce a high quality sparse approximation of the whole signal, using highly coherent redundant dictionaries. The cooperation takes place by ranking the partition units for their sequential stepwise approximation and i...
متن کاملAdvanced Beamforming for Distributed and Multi-Beam Networks
Beamforming entails joint processing of multiple signals received or transmitted by an array of antennas. The design of this technique and the implementation challenges associated with it depend on the configuration of the array itself and on its application objectives, which can be related to a very broad domain of diverse scenarios and engineering problems. This thesis addresses the implement...
متن کاملNode selection optimization for collaborative beamforming in wireless sensor networks
The communication distance and the energy of the nodes are limited in large-scale wireless sensor networks (WSNs). Collaborative beamforming is an effective way to solve such problem. However, the distribution of node location is not uniform, which leads to poor performance of the mainlobe and causes the high sidelobe level (SLL). This paper presents a novel collaborative communication method b...
