A system and electronic device (100) for providing a spread spectrum signal. The device (100) has a modulator (140), digital signal providing circuitry (130) coupled to the modulator (140), a modulation pseudo noise sequence generator (110) having a sequence output coupled to the modulator (140) and an output unit (150) coupled to the modulator (140). In use, the digital signal providing circuitry (130) provides data bits each of which is modulated, by the modulator (140), with a pseudo noise sequence supplied from modulation pseudo noise sequence generator (110) to thereby provide the spread spectrum signal that is transmitted by the output unit (150). There is also a demodulator (170) and input unit (160) for demodulating received spread spectrum signals.
