| Abstract: | In order to accommodate the platform dynamics, the effects of Doppler must be taken into account. This paper brings forward a new kind of digital and practical PN code receiver. In software, with the advanced DSP FPGA technology and the algorithm of FFT to synchronize Doppler, the authors implement a in coherent carrier demodulating receiver, so that the system may achieve PN acquisition and demodulate data timely, and engineers can renovate or upgrade the software on the chips without remodeling the hardware. |
