  • Pre-equalizer for a digitally modulated RF signal and method
    Patent number: 8842720
    Abstract: The method comprises receiving an input stream of symbols (x(i)) representing a phase change and magnitude of an RF signal, the magnitudes of the symbols are constant, the phase changes of the symbols encode digital information, and adjust the input stream of symbols to reduce inter-symbol interference. The adjusting iteratively determines a next symbol of the equalized stream (x?(n)) after receiving a next symbol of the input stream (x(n)) by multiplying the next symbol of the input stream (x(n)) with a next adjusting real number (a(n)), multiplying a previous symbol of the input stream (x(n?1)) with a previous adjusting real number (a(n?1)), the previous symbol being received before the next symbol of the input stream, and the next symbol of the equalized stream is computed from the multiplied next symbol and the multiplied previous symbol of the input stream.
