| Modulation parameters estimation is a key technology in software radio. Carrier frequency estimation and modulation estimation are two main modulation parameters.In this thesis, the principle of some common modulation is discussed. The basic technology and mothods of frequency carrier estimation and symbol rate estimaton are analysed and studied. This paper designs a high speed signal sampling and processing platform. Based on simulation tools of the matlab simulink, some typical modulation analysis methods are simulated. The modulus and some results are given. |
