Channel estimation optimization algorithm based on OFDM system
In recent years,the use of automobiles in people's lives has become more and more widespread,and the rapid growth of the number of cars has caused problems such as traffic congestion and traffic safety.IEEE 802.11p is a communication protocol extended by the IEEE 802.11 standard and is mainly used for in-vehicle electronic wireless communication.In vehicle communication,complex channel environments have high requirements for channel estimation performance.In this paper,a baseband communication system based on IEEE802.11p is established,and several channel estimation algorithms are evaluated in the simulation environment.A weight-based channel estimation algorithm is proposed for training sequences and data pilots in a frame structure.The simulation results show that the algorithm improves l-2dB under the condition of 10-4.
