抄録

Antenna diversity is one of the solutions to multipath fading but with the cost of additional hardware for every RF chain. In mobile reception application, it is difficult to install the additional antennas and cables to the vehicle due to limitations in installation cost and features. In this paper, we propose an Integrated Services Digital Broadcasting - Terrestrial (ISDB-T) diversity receiver using a 4-element electronically steerable passive array radiator (ESPAR) antenna with periodically alternating directivity. The proposed receiver obtains diversity gain requiring only a single-RF front-end and cable, thus reducing the hardware complexity compared to conventional antenna diversity receivers. The receiver utilizes compressed sensing-based channel estimation that recovers the channel state information (CSI) with good accuracy. The simulation results show that with perfect CSI, the proposed ISDB-T receiver is capable of obtaining a diversity gain of about 15 dB for a bit error rate of 10-3.
