This paper analyzes Doppler spectra of mobile-to-mobile (M2M) channels, based on a measurement campaign carried out in an indoor environment at 2.48 GHz. The Doppler spectrum is characterized in line-of-sight (LOS) and non-line-of-sight (NLOS) environments for different types of pedestrian movements. Subsequently, an analytical Doppler spectrum model is proposed and successfully compared to the measurement data.
