摘要：With the increase of the number of wireless devices, the amount of data that needs to be transmitted in wireless network is also increasing rapidly, which brings great burden to wireless transmission. This means device put forward a high requirement for end-to-end wireless communication performance. Therefore, it is very important to further improve the transmission performance. In this paper, we propose the optimal strategy by combining the coherent beamforming (CB) technique and the successive interference cancellation (SIC) technique for improving the performance of wireless device communication. CB technique can be used for expanding the communication range of wireless transmitters, and SIC technique can be used for improving the receiving ability of wireless receiver. We first give the mathematical model based on CB–SIC, find this model is NP-hard in general and cannot be solved directly. Therefore, we design a heuristic algorithm to obtain an approximate optimal solution. In simulation, we compare CB–SIC wireless network with CB only, SIC only, and interference avoidance network. Simulation results show that the algorithm can improve the end-to-end communication performance of wireless network and data throughput has been greatly improved.
