Research on Opportunistic Beamforming Technology in Sparse Network

Abstract:

In this work, an opportunistic beamforming method combined with OFDM technology is proposed to solve the mismatchment of channel beam-forming matrix and vector-matrix in sparse network. Firstly, introduce a two-stage framework, as scheduling and ultimately beamforming, propose beam power control techniques that do not change the direction of the second-stage beams. Then we adapt this scheme to the multi-carrier scenario, such as OFDM systems, in order to improve the whole system’s performance. Simulation results show that this two-stage OBF adjoined to beam power control techniques scheme can improve the total throughput in sparse network system.
