| 摘 要： | 基于Okumura-Hata传播模型，提出了一套新的同频干扰的估算方法，它考虑了移动通信中随机信道的特点、时间和地点概率、随机信号的非相干性、天线高度、发射功率、天线增益、路径距离以及蜂窝频率复用模式等多种因素对载干比得影响，同时在研究中还兼顾到不同地形地貌对信号的影响、单个干扰源和多个干扰源对信号接收的影响，提高了干扰计算的准确度和可信度。

| Abstract: | Based on the propagation model of Okumura-Hata, a new set of estimation methods has been proposed for co-frequency interference, and various factors have been taken into account for the calculation of inference for C/I ratio, such as characteristics of random channel, time and location probability, incoherence of random signals, altitude of antenna, transmitting power, gain of antenna, distance and frequency multiplexing in mobile telecommunications. With this method, the accuracy and reliability for calculation of interference can be increased considerably. |
