Abstract
As to the existing methods for the modulation in the digital communication field, a new hybrid modulation method based on the frequency and phase is presented in this paper. In the signal modulation process, two different sequences are transmitted and then converted into the baseband signal using the Pulse Amplitude Modulation (PAM). The baseband signal are imparted to a carrier wave by varying the phase and frequency of carrier respectively, so that the modulated signal's phase and frequency have the information of baseband signal. In the signal demodulation process, recover the baseband signal through different demodulation algorithm for phase and frequency. From a large number of simulations, the presented method greatly improves the bandwidth efficiency by transmitting two different sequences effectively under the same bandwidth.
