FREQUENCY SHIFT KEYING RECEIVER FOR MINIMUM SHIFT KEYING, AND A METHOD FOR SETTING REFERENCE PN SEQUENCE FOR FREQUENCY SHIFT KEYING THEREOF

摘要

The invention relates to an FSK receiver for MSK capable of transmitting an MSK-modulated signal via FSK demodulation, and a method for setting a plurality of reference PN sequences thereof. In the FSK receiver for MSK of the invention, an RF converter converts an MSK-modulated RF signal into an IF signal. An FSK receiver FSK-demodulates the IF signal into a chip signal. Also, a correlation array includes an FSK PN sequence table comprising a plurality of reference PN sequences having a plurality of FSK reference chip signals. The correlation array collects the chip signal from the FSK receiver to generate a plurality of PN sequences having a plurality of chip signals, and correlating the generated PN sequences with each of the reference PN sequences to restore raw data. The invention provides the method for setting the plurality of FSK reference PN sequences in the FSK receiver for MSK.
