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 1):
A portable spread spectrum audio receiver configured to receive and store a unique user code, said portable spread spectrum receiver configured to receive wireless modulation transmissions from a spread spectrum transmitter, said wireless modulation transmissions representative of an audio signal representation, said portable spread spectrum audio receiver comprising:\n a direct conversion module configured to receive wireless modulation transmissions representative of said audio signal representation and which have been processed to reduce intersymbol interference, and wherein said portable spread spectrum audio receiver further processes said received wireless modulation transmissions for reduction of intersymbol interference; a digital-to-analog converter (DAC) configured to provide an analog audio output signal corresponding to said audio signal representation; a speaker configured to generate an audio signal corresponding to said analog audio output signal, wherein said generated audio signal does not include audible audio content originating from any audio signals transmitted in a spectrum used by said spread spectrum transmitter that do not originate from said spread spectrum transmitter; wherein said portable spread spectrum audio receiver is configured to use independent code division multiple access communication and to use said unique user code to communicate with only said spread spectrum transmitter during a wireless connection; wherein said portable spread spectrum audio receiver is further configured to perform at least one of a plurality of demodulations on at least one of said received wireless modulation transmissions and generate a demodulation signal based on said performance of at least one of said plurality of demodulations, wherein said plurality of demodulations includes a differential phase shift keying (DPSK) demodulation and a non-DPSK demodulation; and wherein said further processing for reduction of intersymbol interference is separate from said performance of at least one of said plurality of demodulations.
