Abstract: The dual modulation compound system (DMCS) in reentry telemetry is analyzed.In this system,two kinds of modulation,Pulse Position Keying/On Off Keying (PPK/OOK) and Pulse Code Modulation/Frequency Modulation (PCM/FM) are employed simultaneously.The conclusion shows DMCS can obviously improve the channel capacity compared with that of PPK/OOK system.
