基于能量检测的频谱感知.由于实际信道中的多径和阴影效应,单个认知用户频谱感知的性能受到影响,因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制,即两用户进行协作频谱感知,提高主用户的检测率,减少检测时间,并且得到捷变增益。要求给出仿真结果。(spectrum sensing in cognitive radio based on energy detection.As the channels in diameter and shadow, not a single user spectrum of capabilities and therefore need different between a user to the spectrum is perceived as more and the effect. this design for the use of a coordination mechanism, the two users collaborate spectrum, the detection rate of increase and decrease the test of time and get a change requires immediate gain. some emulation.

v_resample
V_RESAMPLE is a Matlab function implementing nonuniform data sampling. It resamples the input data at the specified, continuously variable sampling rate, which may be locally higher or lower w.r.t. the original rate. Aliasing terms are taken care of by appropriate smoothing.
