description The invention discloses a frequency variable spread spectrum modulation method and modulator and a frequency variable spread spectrum demodulation method and demodulator. The frequency variable spread spectrum modulation method comprises the steps of determining bit information needing to be transmitted, wherein the bit information comprises N bit sequences, and the N is a positive integer; generating N modulation signal components in one to one correspondence with the N bit sequences, thereby obtaining corresponding modulation signals, wherein different bit sequences in the N bit sequences correspond to different modulation signal components, and the modulation waveforms corresponding to different modulation signal components have different characteristic information; and modulating carrier signals through utilization of modulation signals, thereby obtaining corresponding modulated signals. According to the methods, the modulator, the demodulator, the information quantity contained in the modulation signals
