Abstract: Aiming at the problem of low spectral efficiency and insufficient network throughput in wireless communication network,a space-time quadrature hybrid relay communication network coding algorithm (QHNR) was proposed.The algorithm analyzes the relay communication mode on the MAC phase and BC phase during transmission cycle through the system model and the error rate while the nodes send data.The method of grading gain is used to improve channel utilization efficiency and promote the system performance,and then chooses the better relay nodes via relay probability.The performance of QHNR algorithm was analyzed by both network throughput and network power allocation.The experimental simulation results show that ,compared with the TWR communication scheme and MWR communication scheme,QHNR algorithm has better results in improving the network throughput and promoting channel utilization efficiency.
