摘要

针对DTMB标准，本文通过实验室测试对选定的9种接收机的性能进行了评价，并完成了甚高频(VHF)和超高频(UHF)频段下DTMB接收机的对比测试。测试结果表明，在两个频段下，DTMB接收机的大部分性能基本相同，但有些性能存在显著差异。本文研究了性能随频率的变化趋势及产生相关现象的原因。

Performance Evaluation for DTMB Receiver under VHF and UHF Bands

For DTMB standard, 9 selected performances of the receivers by laboratory tests are evaluated in this paper, while the comparison tests of DTMB receiver under very high frequency (VHF) and ultra high frequency (UHF) bands are also completed. The test results show that most of the performances of DTMB receiver are basically the same under the two bands, but some performances are significantly different. This paper investigates the trend of performance with frequency and the reason for related phenomena as well.
