The Power Spectrum and Its Generation for One kind of Colored Gauss Noise
Lin Jin-zhao · Journal of Circuits and Systems · 2001
The colored gauss noises (CGN) with deterministic power spectrum shapes are usually used to simulate the fading characteristics of wireless channels. The power spectral density (PSD) and its restricted form for radio channel suffering the fast fading is discussed and the spectral specialty and auto-correlation function of the wide band gauss process are analyzed. The time correlation of the shadowing channels with slow fading characteristics are also investigated. The wide band CGNs are approximately generated by means of finite sums of properly weighted sinusoids with uniformly distributed phases, and the Doppler parameters including the Doppler frequencies and Doppler coefficients are determined.
