Mobile Geographic Information Service for 4G Terminal

The mobile geographic information service (GIS) is the key technology to realize navigation. In this study, a transmission method of services under 4G terminal grounded on channel Porter interval equalization algorithm proposed. multisensor collection vehicle networking adopted data and structure characteristics analysis GIS terminal. Subsequently, model constructed. Furthermore, interference suppression in process terminals realized by using an autocorrelation matching filter adaptive association rule mining algorithm. According symbol feature distribution terminal, approach implemented segmented adjustment GIS. K-means clustering procedure also coordinate packet within background dynamic center, adaptively controlled reduce influence fading intersymbol caused spreading. simulation outcomes express that suggested technique has strong anti-jamming ability, reduces communication error rate, significantly diminishes end-to-end delay performance, improves stability accuracy
