ARQ Protocols in Cognitive Decode-and-Forward Relay Networks: Opportunities Gain
Zongsheng Zhang; Qihui Wu; Jinlong Wang (Společnost pro radioelektronické inženýrství, 2015-04)In this paper, two novel automatic-repeat-request (ARQ) based protocols were proposed, which exploit coop- eration opportunity inherent in secondary retransmission to create access opportunities. If the signal was not ... -
Sensing Task Allocation for Heterogeneous Channels in Cooperative Spectrum Sensing
Qihui Wu; Han Han; Jinlong Wang; Zhitao Zhao; Ze Zhang (Společnost pro radioelektronické inženýrství, 2010-12)In the traditional centralized cooperative spectrum sensing, all secondary users sense the same channel. But, for a given channel, there exists detection performance diversity among all the users, due to the different ...
