Cognitive Pilot Channel 感知导频信道
Secondly, the uncertainty during the process of the spectrum detection is caused by the random of the channel in the Cognitive Radio network.
其次,在认知无线电网络中,由于信道的随机性,造成频谱检测过程中的不确定性。
Cognitive radio can effectively improve the utilization of spectrum through dynamic spectrum access technology, in which the channel selection affects directly the performance of the system.
认知无线电可以通过动态频谱接入技术来有效的提高频谱的利用率,而在动态频谱接入中信道选择策略的优劣直接影响着系统的性能。
The selection of control channel in cognitive radio is essential because the control channel has to coordinate all the secondary users via spectrum holes.
因认知无线电通过频谱空洞作为控制信道并且控制信道承担传输全部从用户控制信息,所以控制信道的选择处于重要地位。
