Claim 2:
3. The apparatus of claim 1, wherein the first downlink speech process path further comprises an RX speech data processor and a digital-to-analog converter, 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, the digital-to-analog converter is arranged operably to convert the inverted speech data into the first analog signal, and the inverter is coupled between the RX speech data processor and the digital-to-analog converter, and is arranged operably to receive the first processed data from the RX speech data processor, invert the first processed data to generate the inverted speech data based on the first compensated data generated by the first PLC processor, and output the inverted speech data to the digital-to-analog converter, and wherein the digital-to-analog converter is arranged operably to convert the inverted speech data into the first analog signal to be played by the first speaker.
