Secondly, the optimal design of discontinuous spectrum sensing scheme was studied, which aimed at minimizing the spectrum opportunities discovery time while satisfying the sensing overhead constraint.
其次研究了非连续频谱感知策略的优化设计问题,即在满足感知开销限制的条件下,如何最小化空闲频谱发现时间。
This scheme uses smooth wave instead of discontinuous wave, so the wave in time field is continuous phase and has good frequency spectrum characteristics.
该方案用平滑的波形来替换前后码元的不连续跳变,从而得到相位连续的时域波形,波形平滑、频谱主瓣窄、滚降速度快。
