It also studies the algorithms of FSK, MSK, GMSK modulation and demodulation mode, and summarizes the general the software modulation and demodulation algorithm.
Having realized the modulation and demodulation algorithm of ASK, FSK, QPSK on the software radio platform, and has provided the modulation and demodulation flow chart and the main part procedure.
