Data Transmission Optimization and AppIication in GNSS Receiver
摘要
Abstract
As the number of tracking channels and correlators per channel which is to lift mitigating multipath error ability increase,the Global Navigation Satellite Systems (GNSS)receiver based on the architecture of FPGA+DSP should have the capability to process multi-system and multi-frequency navigation satellite signals,which need to interactive considerable data between FPGA &DSP.On the customize of the FPGA+DSP platform,the design takes QDMA function of DSP to eliminate the invalid time between continuous data reading and reduce the time of DSP execute data transmission obviously.It makes the number of tracking channel increased from 44 to 96 under the same hardware platform,which meets the design requirement of proj ect.关键词
