Abstract
In this paper we present a fully digital architecture for performing frequency hopping modulation and demodulation. The proposed modulator is composed of a cascade of two polyphase up converter channelizers. The first one performs the digital M-ary frequency shift keying (M-FSK) modulation of the baseband signals while the second one accomplishes the task of hopping the M-FSK modulated spectra under the control of a pseudorandom sequence generator. On the receiver side, two dual down converter channelizers undo the frequency shifts performed by the digital channelizers in the transmitter. Synchronization is a key aspect in frequency hopping systems. Transmitter and receiver must both know the hopping pattern and they must be finely synchronized in order to capture the desired information. In this paper we provide a fully digital synchronization architecture that, embedded in the proposed channelizer-based receiver, performs signal acquisition and tracking.
