Transversal equalizer for the TDMA Intelsat services

The considered transversal equalizer applies to a quadraphase shift keying (QPSK) system. Attention is given to the principle of operation, a block diagram of the transversal equalizer, the delay lines, an equivalent baseband model for a linear QPSK systems, an equivalent baseband model for a transversal equalizer component, aspects of RF summing, and test results. The tests performed in a fully-developed engineering model of the equalizer provide a verification of the desired features established as design goals.
