OPTIMIZATION OF WIRELESS NETWORK DATA TRANSMISSION CHANNEL BASED ON SIMILARITY MEASURE
摘要
Abstract
In the process of wireless network data transmission and communication, the routing network damage and communication between symbols inter-symbol interference leads to data transmission channel imbalance.In this case, anti-jamming filtering and equalization design is needed for the data transmission channel of the wireless network to realize the high-fidelity transmission of the wireless network data.The traditional method uses the composite link coherent equalization algorithm to optimize the wireless network data transmission channel.With the increase number of carriers in the communication channel, the channel equilibrium stability is not good.In this paper, we propose a data transmission channel optimization algorithm for wireless network based on the similarity metric of data communication.By constructing wireless network system model and channel model, the similarity measure and feature extraction of data information in wireless network are implemented.In this case, we use IIR filtering algorithm to realize the implementation of channel interference symbol filtering and improved anti jamming algorithm.To achieve the data transmission channel optimization and balanced design of the wireless network, and improve the fidelity transmission capability of the data communication code.Simulation results show that the algorithm can effectively realize the optimization of data transmission channel construction of wireless network, and the channel equalization performance and anti-jamming performance is better, reducing the bit error rate of data transmission.关键词
