Research on capacity region of Gaussian degraded relay broadcast channel

open access: yes上海师范大学学报. 自然科学版, 2017
Considering the relay broadcast channel (RBC),the transmitter communicates with two receivers with the assistance of a relay.Based on degradation orders among the relay and the receiver outputs,three types of physically degraded RBCs (PDRBCs) model are ...

Multi-channel broadcast protocol for CRSN based on home channel

open access: yesTongxin xuebao, 2013
In the light of the limited resources and the dynamic pectrum distribution in the CRSN, a half duplex mul-ti-channel broadcast protocol for CRSN was proposed based on the home channel theory. In the absence of the common channel and clock synchronization,
