METHOD AND APPARATUS FOR PARAMETER ESTIMATION, MODULATION CLASSIFICATION AND INTERFERENCE CHARACTERIZATION IN SATELLITE COMMUNICATION SYSTEMS

摘要

A digital signal processing (DSP)-based approach to parameter estimation modulation identification and interference charaterization in connection with a satellite Communication Monitoring System (CSM). The techniques descried here also allow automatic generation of satellite frequency plans (S74) without any a priori knowledge of such plans. Individual processes for carrier isolation (S71), segmentation (S72), frequency estimation (S73), symbol rate estimation, bit error rate estimation, modulation identification and interference characterization are disclosed may be combined in a totally automated process.
