Abstract: An electronic device (100) for providing a multi-carrier spread spectrum signal. The device (100) has a spread spectrum signal encoder (140) and decoder (160). The encoder has sequence spreading modules (143) and modulators (145) each having a unique carrier frequency relative to all other carrier frequencies of the other modulators (145). The encoder (140) converts a received serial data stream of bits into a plurality of parallel data bit streams of different bit lengths, and expand a received one of the parallel data bit streams into a coded bit sequences. Each of the coded bit sequences have a unique time period relative to all other said coded bit sequence from every other sequence spreading modules (143) of the encoders (140). The decoder (160) decodes received multi-carrier spread spectrum signals into data bit streams.

Abstract: 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.
