Compressed wavelet packet-based spectrum sensing with adaptive thresholding for cognitive radio
Cognitive radio is a system to utilize spectrum holes efficiently as a solution of spectrum scarcity. The availability of channels for secondary users is determined in the spectrum sensing phase by energy detection. Energy levels of sampled primary user's (PU's) signal can be measured by w...
