频谱感知技术是认知无线电技术里最关键和最具挑战性的技术-Spectrum sensing is a key technology in Cognitive
Radio (CR). It provides the CR system with available vacant
channels list by sensing the spectrum environment over a wide
frequency band. However, local sensing by

A typical format for a DPPM signal
in a UWB system is derived that of a PPM signal.
The error probabilities of DPPM with receive diversity
over additive white Gaussian noise (AWGN) channels and
Nakagami fading channels are analyzed.-A typical

Channel estimation for millimeter-wave (mmWave)
massive MIMO with hybrid precoding is challenging, since the
number of radio frequency (RF) chains is usually much smaller
than that of antennas. To date, several channel estimation schemes
have bee
