| Abstract: | Based on SDR theory, this paper introduces the digital direct sequence spread spectrum(DSSS) receiver channel design of airborne VHP broadcasting station using HSP50110, HSP50210 and FPGA. HSP50110 and HSP50210 chips are ideal for achieving demodulation applications with multiple demodulating modes such as PSK, FSK, FM and AM signal.Especially this paper introduces a new FPGA algorithm of capture and tracking of Pseudo Noise(PN) code .The capturing time is less than 1 PN cycle, and the immunity margin is more than 80dB. |
