手机电视终端天线接收性能评估方法研究
Study on Antenna Receiving Performance of Mobile TV Device
摘要 广播式的手机电视终端天线基于单向通信模式,传统的天线接收性能评估方法对其不适用。针对手机电视技术的特点提出了主观测试方法、误码率读取法、图像采集法三种不同的天线性能评估方法,对各种方法的优劣进行了解析。得出图像采集法准确度高,不确定度低,对被测终端没有特殊要求,且容易实现自动化测试,是目前较为理想的评估手机电视终端天线接收性能的方法。

Abstract Because of one-way communication,traditional antenna receiving performance
evaluation method is not applicable to device supporting mobile multimedia broadcast
service. After considering the characteristic of mobile TV, three different
evaluation methods are analyzed including subjective method, error bit rate reading
method and image collection method.It can be concluded that image collection method
is a better evaluation method so far because its high accuracy and low uncertainty and
it have no special requirement for EUT. Also automatic test can be achieved easily using
this method.
