Wireless digital audio system

An audio receiver for packaging in a headphone comprising:

• a receiving antenna in communication with a wideband band pass filter;
• said wideband band pass filter in communication with a direct conversion receiver the output of which is summed with a receiver code generator in a receiver summing element;
• said receiver summing element in communication with a demodulator the output of which is in communication with a block de-interleaver;
• said block de-interleaver output in communication with a Viterbi decoder the output of which is in communication with a source decoder;
• said source decoder output in communication with a D/A converter the output of which is in communication with an analog low pass filter;
• and
• said analog low pass filter output in communication with a power amplifier the output of which is in communication with a headphone speaker.

A wireless digital audio system for wireless transmission of a signal from an audio source to a headphone comprising:

• a headphone plug in communication with an analog low pass filter and connectable to a headphone jack of an audio source;
• said low pass filter output in communication with an A/D converter;
• said A/D converter in communication with a digital low pass filter, the output of which is in communication with an encoder;
• said encoder output in communication with a channel encoder the output of which is in communication with a block interleaver;
• said block interleaver output in communication with a modulator the output of which is summed with a transmitter code generator output in a summing element;
• said summing element output in communication with a differential phase shift key transmitter the output of which is in communication with a transmit antenna for wireless transmission of a signal to a receiving antenna;
• said receiving antenna in communication with a wideband band pass filter;
• said wideband band pass filter in communication with a direct conversion receiver the output of which is summed with a receiver code generator in a receiver summing element;
• said receiver summing element in communication with a demodulator the output of which is in communication with a block de-interleaver;
• said block de-interleaver output in communication with a Viterbi decoder the output of which is in communication with a source decoder;
• said source decoder output in communication with a D/A converter the output of which is in communication with an analog low pass filter;
• and
• said analog low pass filter output in communication with a power amplifier the output of which is in communication with a headphone speaker.
