Digital Signal Generation for Orthogonal Chirp Signal
Yuming Du · Journal of Sichuan Normal University · 2005
In this paper,a new method of digital signal generation for orthogonal chirp signal is provided.The algorithm is with low computational complexity and very low memory.Time-varying parameters of the ARMA model in this paper processes chirp signal,it avoid computation of sinusoidal function in chirp signal generation and phase truncation.By using this Time-varying parameters ARMA model,real time processes signal,checking or searching tables is not needed,so it can do well data word-length and reduce error consumedly in amplitude quantization.
