Gauss White Noise in Digital Frequency Modulation Scheme

This chapter introduces the scheme about how to generate the band-limited Gauss white noise digital FM signal scheme. Firstly, generate pseudorandom sequence, then transform the pseudorandom from the Uniform distribution to the Gauss distribution, then do low-pass filtering. Finally, realize digital FM processing by the method of direct digital frequency synthesis (DDS). The simulation results show that the scheme can generate effective Gauss white noise signal.
