Rearch Of Wireless Communication Technique Based MIPS Structure

WLAN technology is wireless local area networks by wireless channel transmission medium, which realizes the link with wide-band network, quickly and easily resolves the link of the network channel nowhere notime. The transmission of physical of WLAN is a hot-resolving problem in the field of wireless long-way communication.This paperdiscuss the Freqence Hoppingvies of the Spread Spectrum Communication,The transmission technology and system of physical of wlan based on MIPS Structure theory, design a system of communication system of WLAN ends that makes extendthe capacity of WLAN system.In paper, Introduces physical technology of WLAN , presents the Designing, Realizing and Theory of FH-OFDM technique, and simulinks the module of the physical system by software of Matlab,In orde to realize the simulink of FH-OFDM system. Analyzes and processes the results of the simulink, Finally Put the technology to use of designing wireless-NetCard,In addition to construct a complete VoWLAN ends.In course of the rearch , comparises between module/demodule based single OFDM and FH-OFDM, recovers some problem in module/demodule based single OFDM, applies the module/demodule based FH-OFDM in VoWLAN end which will be a more performance communication system.
