Traditional satellite navigation receivers usually depend on FPGA chips or ASIC chips, which lack flexibility and multiple constellation support. The paper presents a single DSP multi-constellation satellite navigation receiver hardware design method, and discusses signal sample, buffer and output technology. Furthermore, multi-constellation task scheduler is also discussed. Based on TMS320C6416,...
13 lines including 9 wheat mutants of genetic transformation by ion beam and 4 acceptor control varieties were analyzed by SSR marker. A special band of dwarf mutant line 1042 was obtained, sequenced and analyzed by blast software. The genetic distance was analyzed with SSR marker materials by SAS software. The result showed that 9 wheat mutants were clustered together with their own acceptor control...
Compare to previous GNSS receiver, this paper present software defined radio approach to implement the 12 channel GPS receiver in single DSP platform. Different with previous implementation, only single generic DSP chip will be used to complete all functions of a GPS receiver this time. The paper will introduce design of the system architecture, the realtime algorithms and show how to extend them...
