Abstract
An apparatus and a method for generating voice signals for a wireless communication station. The wireless communications stations includes a receiver, a signal strength measuring device, a filter and a noise generator. The receiver receives a digitally modulated radio voice signal and the signal strength measuring device measures a signal strength of the received radio voice signal. The filter removes noise signals present with the received radio voice signal when the signal strength is below a predetermined threshold, and the a noise generator generates a noise signal for combination with the received voice signal.
