Improved Design of Pseudo-Code Tracking Algorithm Based on Numerically Controlled Oscillator in FPGA

1 Introduction Direct sequence spread spectrum technology has been widely studied and applied in the fields of communication, navigation, measurement and control. The spread spectrum modulation system requires the exact same pseudo-random code to be used for spreading and despreading at both ends of the transmitter and receiver. Therefore, the precise synchronization between the receiver’s […]
