摘要

减少二次用户的干扰是频谱共享中最具挑战性的问题之一。在本文中，我们推导出最佳的传输策略，使认知无线电在给定的空间点(即主接收器的位置)产生的平均干扰功率最小。令人惊讶的是，这不是由充水溶液给出的。

Optimum cognitive radio transmission scheme for reducing average interference power

Reducing interference induced by secondary users is one of the most challenging problems in spectrum sharing. In this paper, we derive the optimum transmission strategy that minimizes the average interference power created by cognitive radios at a given point of space i.e. the location of a primary receiver. Surprisingly, this is not given by the water-filling solution.
