摘要

研究了在给定信道分配条件下，控制发射机功率以减少同信道干扰的方法。从干扰的角度对性能进行了分析。(中断)的概率。提出了Qpthm和近最优全局功率控制方案。利用这些方案推导了功率控制方案性能的上界。数值结果表明，这些上界在抑制干扰方面比传统系统的性能好一个数量级，在容量方面比传统系统的性能好5倍。优化算法的结构表明，有效的功率控制和动态信道分配算法应该密切相关。

Optimum Global Transmitter Power Control in Cellular Radio Systems

Transmitter power control as a method to reduce cochannel interference for a given channel allocation is investigated. The performance is analyzed in terms of interference. (outage) probabilities. Qpthm and nearoptimum global power control schemes are proposed. Using these schemes upper bounds on the performance of power control schemes are derived. Numerical results indicate that these upper bounds exceed the performance of conventional systems by an order of magnitude in interference suppression and by a factor of 5 in capacity. The structure of the optimum algorithm shows that efficient power control and dynamic channel assignment algorithms should be closely related.
