阵列天线是提高移动的通信性能的一种很有吸引力的方法。在本文的应用中，为了提高移动的ISDB-T接收机的接收质量，在汽车上设置了四个天线单元。针对每个天线的方向特性，提出并实现了一种适用于移动的ISDB-T接收机的预FFT自适应阵列天线和后FFT空间分集合并（AAA-SDC）方案。仿真结果表明，AAA-SDC方案大大提高了移动的ISDB-T接收机的性能，特别是在高速移动条件下。在现场进行的实验结果也证实，所提出的AAA-SDC方案成功地实现了出色的接收率高达100%，而在高速公路上以80公里/小时的速度移动。
Array antenna is an attractive method to improve the performance of mobile communication. In our application targeted here, four antenna elements are set in an automobile to improve the reception quality of mobile ISDB-T receiver. With regard to the directional characteristics of each antenna, we propose and implement a joint Pre-FFT adaptive array antenna and Post-FFT space diversity combining (AAA-SDC) scheme for mobile ISDB-T receiver. Simulation results show that the AAA-SDC scheme drastically improves the performance of mobile ISDB-T receiver, especially in high-speed moving condition. The experimental results conducted in the field also confirm that the proposed AAA-SDC scheme successfully achieves an outstanding reception rate up to 100% while moving at the speed of 80 km/h in a highway.
