This paper presents a novel digital beamforming to improve channel quality. By estimating the received channel impulse response (CIR) to calculate the arrival of angle (AOA) of received signal, and we scan the AOA to adjust the weighting vector of received signal and improve the channel quality. The performance of system with digital beamforming can improve 16 dB signal to noise ratio (SNR) in non-line of sight (NLOS).
