A Wavefront Launching Model for Predicting Channel Impulse ResponseAbstract
Maintaining the topology of an expanding wavefront surface allows for a simpler time-domain wave ray launching model that is free from the problems associated with ray catching. In addition to the usual ray location and direction information, the wavefront launching model stores which rays are adjacent in the advancing wavefront surface. The added information allows interpolation over this surface, so the model easily incorporates diffracted waves and power density changes from beam spreading.
