  • System and method for equalization of forward and reverse channels of a communication network system
    Patent number: 5608728
    Abstract: A system and method for equalization for forward and reverse channels of communicating highway network system having a branching tree topology. The system and method cause the forward channel to be adjusted first for equalization, then the reverse channel is adjusted for equalization. A reference node periodically transmits a frequency-rich signal on the network to the head end, which broadcasts this signal to each of a number of system nodes. Each system node compares the frequency-rich signal with an expected signal, and adjusts its receiver based on this comparison. Next, each system node transmits another frequency-rich signal to the head end, receives a return echo, compares the echo with the transmitted signal, and adjusts its transmitter based on the comparison.
