The digital baseband shaping filter based on Gaussian filter

In the process of the digital base-band transmission, in order to eliminate the intersymbol interference and achieve the objective of the base-band shaping filter, in this paper based on Gaussian filter designed a digital realization method of the base-band shaping filter is introduced. First of all, it introduces commonly used the base-band shaping filter in digital system. Secondly, through the design shaping filter weight function, to make the base-band shaping filter to reach the best results. At last, got the designed of the Gaussian filter by programming and simulation in MATLAB. And this outcome demonstrates that the base-band shaping filter designed by this scheme can perfectly achieve the shaping performance of the signal in the communication system.
