Abstract
Demodulation of CPM-modulated information symbols which are demodulated after being transmitted through an AWGN channel, using only partial whitened matched filtering, whereby finite pulses are produced which, however, are still accompanied by interferences in the form of remaining colored noise which can be approximately converted into white noise by a successive additional whitening filter so that the noise power will be minimized. For correcting the accompanying symbol interferences, a sequence estimation with reduced number of states follows.
