Abstract
A radio receiver () adapted to receive an AM-MSK modulated carrier signal includes an envelope detector () and a transformer () which restores the real signal to complex MSK format. A Doppler remover () removes any Doppler shift of the MSK due to relative motion of the transmitter and receiver (). A sample rate reducer () may reduce the sample rate used in the Doppler remover () to the transmitted symbol rate used during the modulation process.
