Research on Ofdm and the Single Carrier Signal Modulation Recognition

In recent years, the communication technology is developing rapidly and the way of the modulation of communication signals is sundry. Therefore, it is become very meaningful to do some research on OFDM and single carrier signal modulation recognition between class, as well as the single carrier signal modulation recognition within class. However, most traditional algorithms of these two types modulation recognitions are complex and have a big calculation. So it is very necessary to make improvements and reduce the computational complexity of the algorithms. This thesis does some analysis on the traditional method to reduce the computational complexity by extracting the new characteristic parameters.
