METHODS AND APPARATUS FOR AUTOMATIC SWITCHING BETWEEN TRANSMISSION OF A SPECTRALLY REDUNDANT OUTGOING SIGNAL AND RECEPTION OF AN INCOMING SIGNAL

摘要

An improved method and apparatus for automatic switching between transmission of a spectrally redundant outgoing signal and reception of an incoming signal when communicating through a partially reflective bidirectional communication channel. Filtering methods and apparatus are utilized to attenuate from the transmission of the outgoing signal components which are within a spectrum of the incoming signal such that echoes of the outgoing transmission do not interfere with the detection of the incoming signal.
