Demodulate CPM-modulated data
Communications Toolbox / Modulation / Digital Baseband Modulation / CPM
The CPM Demodulator Baseband block demodulates a signal that was modulated using continuous phase modulation (CPM).
CPM is a modulation method with memory. The block processing includes a correlator followed by a maximum-likelihood sequence detector (MLSD) that searches the paths through the state trellis for the minimum Euclidean distance path. The block uses the Viterbi algorithm to perform MLSD.
For more information about this demodulation and the filtering applied, see CPM Demodulation and Pulse Shape Filtering.
