| Abstract: | 2CPFSK and BPSK are two main ways of modulation in UAV radio data link telemetry and telecontrol system. It introduces a method to complete achieve 2CPFSK and BPSK digital modulation option based on DDS chip AD9854,and gives the principle of circuit design and methods of hardware implementation. The design accomplished digitization and modularization of the UAV radio IF of telemetry and telecontrol system,improved the telemetry and telecontrol channel transmission capacity. Through the UAV flying applicatio... |
