摘要
中国移动多媒体广播(CMMB)网络分析已经提到中国各地运营商的日程上来。介绍了单频网及网络结构,通过对测量参数的介绍,详细分析了CMMB无线网络。在此基础上,提出了3个方面的分析:覆盖分析、画质分析和同频网络分析。通过实际测量的数据和路测图,分析了CMMB单频网络,为CMMB网络优化提供了基础。
The China Mobile Multimedia Broadcasting （CMMB） network analysis has been mentioned on the agenda of Chinese company. Single-frequency network and network architecture of CMMB are studied first,through the introduction of the measured parameters, CMMB network is analyzed in detail. On the basis of analyzing has present the following three aspects which contain coverage analysis, quality analysis and network analysis of the same frequency. Based on actual measurement data and road mapping, the single-frequency network of CMMB is analyzed, which is able to provide a basis for CMMB network optimization.
