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

Symbol and Bit Error Probabilities of Orthogonal Space-Time Block Codes with Antenna Selection over Keyhole Fading Channels

中继信道下 利用EXIT算法进行中继选择， Lajos Hanzo 实验室的成果(In this paper, we have proposed and investigated an attractive joint source coding, channel coding, and modulation (JSCM) scheme for a two-way relaying system. We commence by quantifying the achievable capa

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
