Abstract:
1. A method for wireless digital audio transmission and reception of at least one audio source between at least one digital portable audio transmitter and at least one portable audio receiver comprising the steps of: operatively coupling the digital portable audio transmitter to said at least one audio source, the digital portable audio transmitter comprising: converting the audio output to a digital communication signal; encoding the digital communication signal; filtering the digital communication signal; creating the DSSS signal; transmitting the DSSS signal to said at least one portable audio receiver configured for digital wireless communication from said at least one portable digital audio transmitter and utilizing an embedded fuzzy logic detector wherein the fuzzy logic detector activates fuzzy logic rules and performs a defuzzification operation in response to a received user code in said transmitted DSSS signal, said at least one portable audio receiver comprising: receiving said DSSS signal at said at least one portable audio receiver; demodulating said DSSS signal; demodulating said digital communication signal; filtering said digital communication signal; channel decoding said digital communication signal; converting said digital communication signal to an audio output; and communicating the audio output to said at least one portable audio receiver, said audio output having been wirelessly transmitted from said at least one audio source to a user privately without interference from other users or wireless devices when operated in a shared space containing at least one other users of wireless devices utilizing code division multiple access (CDMA) communication.
