Claim 4:
5. The apparatus of claim 1, wherein the first downlink speech process path further comprises an RX speech data processor, a digital-to-analog converter, and the inverter, wherein the RX speech data processor is arranged operably to perform a second algorithm on the first compensated data for improving call quality to generate a first processed data, wherein the digital-to-analog converter is arranged operably to convert the first processed data into a converted analog signal, and the inverter is coupled between the digital-to-analog converter and an amplifier, and is arranged operably to receive the converted analog signal from the digital-to-analog converter, invert the converted analog signal into the inverted speech signal based on the first compensated data generated by the first PLC processor as the first analog signal, and output the first analog signal to be played by the first speaker.
