定量评估了采用FH-MFSK传输的蜂窝移动的系统中邻区干扰的影响。在假设所有小区中的用户之间完全同步的情况下，分析了系统中基站到移动的通信的性能。对无功控系统的分析表明，当平均误比特率Pb <1 × 10- 3时，系统的同时用户数比孤立小区的相应数字（约为170）大大减少。结果表明，一个简单的功率控制策略可以显着降低相邻小区的干扰。合理地了解小区内用户的分布，可以优化接收机阈值与基站的距离。通过这种优化，每个小区可以在Pb< 10-3时容纳10115个用户，确切的数字取决于用户分布。功率控制还有助于降低从基站发送的平均功率。
The effect of adjacent cell interference in cellular mobile system using FH-MFSK transmission is evaluated quantitatively. The performance of base to mobile communication in the system is analyzed, assuming perfect synchronization between users in all the cells. Analysis of the system employing no power control shows that the number of simultaneous users possible at average bit error probability Pbof less than 1 × 10-3is reduced greatly from the corresponding figure for the isolated cell (which is about 170). It is then shown that a simple power control strategy could reduce the adjacent cell interference significantly. A reasonable knowledge of the distribution of users within a cell allows the optimization of the receiver threshold with respect to distance from the base. With this optimization, each cell could accomodate ≳ 115 users at Pb< 10-3, the exact figure being dependent on the user distribution. The power control also helps to reduce the average power transmitted from a base.
