Abstract: A digital demodulation system calculates an I channel value and a Q channel value of a received signal. The digital demodulation system then changes detection levels to obtain non-uniform detection levels. The digital demodulation system then demodulates the received signal bit by bit by using the changed detection levels and the I channel value and the Q channel value.
