Information Sequence Processing with FSK Modulation System
In this system, the information sequence undergoes FSK modulation first, followed by a low-pass filter with 25kHz cutoff frequency to constrain signal bandwidth. The filtered signal is then upconverted via a mixer to higher transmission frequencies. At the receiver, synchronized frequency-hopping signals perform downconversion (de-hopping occurs here), with lower sideband extraction preceding FSK demodulation. Implementation involves digital signal processing algorithms for modulation/demodulation and mixer operations using trigonometric functions.
