GEOMETRIC MODEL FOR DSPN SATELLITE RECEPTION IN THE DENSE SCATTERER MOBILE ENVIRONMENT

A geometric propagation model is developed for simulating the reception of direct pseudo noise (DSPN) satellite signals by a directional or omni antenna in the dense scatterer mobile environment. The model is used to predict fading statistics for DSPN signaling with either omni or directional antennas. expected, the mitigation of fading is closely related to the ratio of DSPN chip duration to delay spread of the scatterer medium for both the omni and directional antennas. The results suggest a general, frequency domain interpretation for the value of DSPN in mitigating multipath fading.
