| Abstract: |
| A low complex algorithm for symbol rate estimation of Multi-h CPM(Continuous-P
hase Modulated) signal is pr
esented.The main contribution in this paper is that a prefilter and sq
uare estimator is derived and its principle is explained using PAM decomposition
of Multi-h CPM signal.Computer simulation results show the unbiased estimator
is robust and it does not need prior informations of carry frequence and modulat
e index. |
