Abstract
Beamforming is one of the most important technologies for wireless communication systems. A beamforming antenna system can control the radiation beam pattern and thus can reduce power consumption, compared with an omni-direction antenna system. In general, the digital beamforming technology requires a complex control system. However, a digital RDA (retro-directive array) antenna system has very small calculation load and its configuration is quite simple as it transmits to a receiving direction without prior information, and simply needs to estimate the phase from an incident. Thus, a RDA antenna system can reduce the system complexity and power consumption, and improve system performance. In this paper, we describe the structure of a digital RDA system and investigate the beam tracking performance of a digital RDA system. It is shown through simulation results that a digital RDA system can effectively improve the beam tracking performance when a target receiver is moving. The mean beam tracking error can reach 1.9° when the SNR is 10 dB and 0.6° when the SNR is 20 dB.
