Claim 3:
4. 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 inverter is coupled between the first PLC processor and the RX speech data processor, and is arranged operably to receive the first compensated data from the first PLC processor, invert the first compensated data to generate the inverted speech data, and output the inverted speech data to the RX speech data processor, wherein the RX speech data processor is arranged operably to perform a second algorithm on the inverted speech data for improving call quality to generate a first processed data, and wherein the digital-to-analog converter is arranged operably to convert the first processed data into the first analog signal to be played by the first speaker.
