Title:
VEHICLE-MOUNTED NAVIGATION CHANNEL ADAPTIVE SYSTEM BASED ON PRE-DISTORTER
Document Type and Number:
WIPO Patent Application WO/2017/036002
Kind Code:
A1
Abstract:
A vehicle-mounted navigation channel adaptive system based on a pre-distorter comprises a microcontroller module, a GPS module, an analog-to-digital conversion module, a power supply module, a pre-filter, a frequency hopping signal processor, an error processor, a time delayer, the pre-distorter, a post-filter, and an antenna. By using an adaptive pre-distortion system, the system compensates vehicle-mounted GPS location positioning, position information collected by a vehicle-mounted terminal can be better transmitted, out-of-band spectrum expansion of a BOC signal can be effectively restrained, out-of-band distortion can be reduced, a constellation diagram is optimized, in-band distortion is reduced, and distortion influences on the BOC signal by the navigation channel can be well eliminated.
