Abstract:
A wireless digital audio system includes a portable audio source with a digital audio transmitter operatively coupled thereto and an audio receiver operatively coupled to a headphone set. The audio receiver is configured for digital wireless communication with the audio transmitter. The digital audio receiver utilizes fuzzy logic to optimize digital signal processing. Each of the digital audio transmitter and receiver is configured for code division multiple access (CDMA) communication. The wireless digital audio system allows private audio enjoyment without interference from other users of independent wireless digital transmitters and receivers sharing the same space.

Claim (Index 17):
A portable spread spectrum audio transmitter configured to transmit a unique user code and wireless modulation transmissions representative of an audio signal representation, said portable spread spectrum audio transmitter configured to:\n encode a first representation of an audio signal to reduce intersymbol interference associated with a transmitted representation of the audio signal; perform at least one of a plurality of modulations on the first representation of the audio signal; generate a modulated signal based on the performance of the plurality of modulations, wherein the plurality of modulations includes a differential phase shift keying (DPSK) modulation and a non-DPSK modulation; and use the modulated signal and independent code division multiple access communication to wirelessly transmit a transmitted representation of the audio signal.
