Power spectral density of duobinary-signalled minimum shift keying (MSK) with arbitrary pulse shaping
V. O. Nkambule, R.H. Braun · 2002
We present a general method for computing the power spectral density (PSD) of a partial-response, continuous phase modulated (CPM), constant-envelope signal. The modulation scheme employed is minimum shift keying (MSK). The frequency modulating signals are a random baseband pulse train in which the arbitrary pulse is time limited. Random data symbols transmitted during different time slots are assumed to be identically distributed and statistically independent.
