Abstract：The pilot reuse interference of wireless communication network is difficult to eliminate, which leads to the security degrade of wireless communication network. To improve the performance of existing pilot reuse interference coordination algorithm, an optimization algorithm for pilot reuse interference coordination is proposed. Firstly, a cellular wireless communication network model is established to analyze the cell interference problem caused by pilot reuse; then the interference probability is calculated to establish the wireless communication network cell interference model; finally, the pilot reuse interference coordination problem is described, which maximizes the equivalent gain of channel based on orthogonal complement space calculation, eliminates the inter-cell interference by dispatching users, and the coordination and optimization of pilot reuse interference in wireless communication network is analyzed. The experimental results show that the designed algorithm has high throughput, the maximum packet loss rate is 7%, the minimum symbol error rate is 13%, and it has certain advantages in terms of outage probability and power difference test. It has a superior overall performance, which provides beneficial support for improving the transmission performance of wireless communication network.
