In recent years, the rapid development of wireless cellular communications has led to increasingly tight frequency resources. Power control and dynamic channel allocation are effective strategies to solve this bottleneck. However, the theoretical algorithms for power control and dynamic channel allocation are quite complicated. Most of them are simulation analyzes. In this paper, the dynamic channel assignment based on power control in wireless cellular communication system is studied deeply. By borrowing the channel algorithm and analyzing the co-channel interference, the concept of interference adaptive factor and its calculation method are put forward. It can be easily and practically calculated that the wireless cellular System capacity. The results show that this channel allocation strategy effectively improves the channel utilization rate, the algorithm is simple, and greatly reduces the complexity of various algorithms in the past. Finally, this article further system simulation, simulation results and theoretical comparison algorithm, a good degree of compliance, the error does not exceed 8%.
