| 摘 要： | 在复杂单频网环境下,延时调整不能完全消除覆盖重叠干扰区,结合上海地区CMMB单频网的实际案例,研究了采取调整发射点发射功率和延时配置方案的可行性。鉴于广播电视发射塔高度高的特点,提出采用调整天线下倾角的方法消除网络中的重叠干扰区,从而使网络整体达到更好的覆盖效果。

| Abstract: | In a complex environment,the interference of overlapping coverage area is not effectively reduced by traditional Single Frequency Network(SFN) optimization.The features of adjusting transmit power and time delay configure of transmitting site of CMMB network in Shanghai is researched in this paper.Considering the high height of the transmission tower,adjusting the antenna declination angle to eliminate the network overlap interference area is proposed,and a better result of overall coverage is achieved. |
