ABSTRACT:
A method and apparatus for transceiving data over a wireless communication path with minimal effects from cross-talk is accomplished by a receiving circuit, a transmission circuit, and an interference cancellation circuit. The receiving circuit includes an amplifier and a scaling circuit which operate upon input data signals to produce a scaled representation thereof having high pulse with fidelity. The amplifier circuit and scaling circuit each include adjustable circuitry which are configured based on the magnitude of the received data signals. The interference cancellation circuit provides a signal to the amplifier circuit and scaling circuit to bias the respective adjustable circuitry to an initial operating level when the transmission circuit is transmitting data and/or upon completion of such transmissions.
