A Cooperative ARQ Protocol Based on Conditional Probability Retransmission
Wei Ji · Journal of Nanjing University of Posts and Telecommunications · 2012
The retransmission process between sender and receiver is assisted by a relay in Cooperative Automatic Repeat request(C-ARQ).We find that in cognitive radio networks with multiple second users,the total second networks throughput increases if the system uses a new C-ARQ protocol based on conditional probability retransmission and implements acknowledgment signals from the relays.
