1. An apparatus for use in a communications system having a receiver that receives a communications signal transmitted by a transmitter, the transmitter including transmitter power control means, responsive to a received power control signal, for controlling a power level at which the transmitter transmits the transmitted communications signal, the apparatus comprising:

  • measurement means for generating a signal strength measurement signal based on the received communications signal;

    means for attenuating the received communications signal by an attenuation amount dynamically determined by a control signal, thereby producing an attenuated signal to be supplied as an input to the receiver;

    attenuation control means, coupled to the measurement means and the attenuating means, for using the signal strength measurement signal to generate the control signal and for supplying the control signal to the attenuating means; and

    first power control means, coupled to the measurement means, for using the signal strength measurement signal to generate the power control signal to be communicated to the transmitter;

    wherein the attenuation control means and the first power control means coordinate with one another to dynamically control, respectively, the attenuation amount and the transmitter power level so as to substantially optimize communications system performance, andwherein the attenuation control means dynamically adjusts the attenuation amount to produce an effective dynamic range for receiving only signals having a signal strength level that is higher than a signal strength level of a disturbance signal, while at the same time the first power control means adjusts the transmitter power level so that the transmitter will produce an adjusted communications signal that is within the effective dynamic range of the receiver.
