Radio receiver AM-MSK processing techniques |
摘要 |
A radio receiver (10) adapted to receive an AM-MSK modulated carrier signal includes an envelope detector (24) and a transformer (28) which restores the real signal to complex MSK format. A Doppler remover (34) removes any Doppler shift of the MSK due to relative motion of the transmitter and receiver (10). A sample rate reducer (56) may reduce the sample rate used in the Doppler remover (34) to the transmitted symbol rate used during the modulation process. |
