Wireless audio receiver system and method

A wireless audio receiver system, comprising:

• (A) a first diversity antenna and a second diversity antenna for receiving one or more of a first radio frequency (RF) signal and a second RF signal, each of the first and second RF signals containing an audio signal modulated using an analog modulation scheme or a digital modulation scheme;
• (B) an RF analog signal processing module in communication with the first and second diversity antennas, the RF analog signal processing module comprising a first RF signal processing path, a second RF signal processing path, and an antenna routing module, wherein the first and second RF signal processing paths and the antenna routing module are configured, based on a user setting that denotes a modulation type of the first and second RF signals and a configuration to full diversity mode or switched diversity mode, such that:
• if the user setting denotes the configuration to full diversity mode, the antenna routing module routes the first RF signal to the first RF signal processing path and the second RF signal processing path, wherein the first RF signal processing path generates a first passband modulated signal based on the first RF signal and the second RF signal processing path generates a second passband modulated signal based on the first RF signal;
• or
• if the user setting denotes the configuration to switched diversity mode, the antenna routing module switches between the first and second diversity antennas to respectively route the first and second RF signals to the first and second RF signal processing paths based on an antenna switching algorithm, wherein the first RF signal processing path generates a third passband modulated signal based on the first RF signal and the second RF signal processing path generates a fourth passband modulated signal based on the second RF signal;
• (C) a first analog to digital converter (ADC) and a second ADC in communication with the RF analog signal processing module, wherein:
• if the user setting denotes the configuration to full diversity mode:
• the first ADC is for passband sampling the first passband modulated signal to generate a first digitized passband modulated signal;
• and
• the second ADC is for passband sampling the second passband modulated signal to generate a second digitized passband modulated signal;
• and
• if the user setting denotes the configuration to switched diversity mode:
• the first ADC is for passband sampling the third passband modulated signal to generate the first digitized passband modulated signal;
• and
• the second ADC is for passband sampling the fourth passband modulated signal to generate the second digitized passband modulated signal;
• (D) a first digital signal processing (DSP) module in communication with the first ADC and a second DSP module in communication with the second ADC, wherein:
• the first DSP module demodulates the first digitized passband modulated signal, based on the user setting, to generate a first digital audio signal;
• and
• the second DSP module demodulates the second digitized passband modulated signal, based on the user setting, to generate a second digital audio signal;
• (E) a first digital to analog converter (DAC) in communication with the first DSP module and a second DAC in communication with the second DSP module, wherein:
• the first DAC generates a first analog audio signal from the first digital audio signal;
• and
• the second DAC generates a second analog audio signal from the second digital audio signal.
