ABSTRACT:
This invention pertains to a digital modem having a normalizer for normalizing the output of the modem demodulator to a predetermined range. The modem generates a signal vector corresponding to each received signal in a complex plane. The normalizer then generates a normalizing factor corresponding to the radius of the signal vector which then is multiplied with the demodulator output.
