“…The paths between a signal source and DOA sensors are calculated using ray tracing based on geometric optics. Ray launching has been one of the most popular techniques for modeling the radio channel and predicting the radio wave propagation at high frequencies . We applied the ray launching method shown in Fig.…”

“…For indoor environments, however, these methods must be implemented in a three-dimensional code, for which the number of traced rays becomes critical, as it is directly related to required computation times [3]. Various techniques have been proposed to reduce the number of traced rays, like the use of a receiving sphere [4], or the big ray tracing technique [5][6][7]. For the same goal, this Letter proposes another technique, which allows sufficiently accurate, fast computation of fields in a multireflecting environment.…”
