- Abstract
- In this thesis, beam alignment problem in analog beamforming system is studied.
By exploiting vision information obtained from RGB camera, joint Tx-Rx beam
tracking system can be implemented. Angles required for beamforming is estimated
by some image processing methods. The proposed method determines the best beam
pair through the estimated angles the user equipment is located. Aftermath, it is
empirically observed that the proposed system attains stable data rates in real time.
Compared to conventional method, which is called exhaustive method, the proposed
method can outperform in terms of the coordination-free property. Determining
the optimal beams without feedback from the receiver saves resources which
should have allocated to data transmission. The proposed method can be usable to
latency sensitive applications which needs 5G communication.
