Research on a Method of Obtaining the Optimized Signal Using Pan-function Modeling

In order to obtain the higher roll off of energy spectrum of base-band symbol signal, through the application of the minimum frequency out-band energy exposure guidelines, establish an optimized base-band symbol signal mathematical Pan function model, at the same time, add the restrictions on boundary conditions of symbol, base-band symbol signals energy and signals PAPR on the mathematical pan function, we realize the solving process of the optimized signal. Compared with the conventional rectangular signal and cosine signal, the resulting signal has more advantages in the spectral characteristics.
