Analytically derived TOA-DOA statistics of uplink/downlink wireless multipaths arisen from scatterers on a hollow-disc around the mobile Academic Article uri icon

abstract

  • The paper rigorously derives explicit closed-form expressions for the joint/marginal probability density functions of the uplink/downlink multipaths’ time-of-arrival (TOA) and azimuth angle-of-arrival (AOA) in a wireless-communication fading channel. This derivation is based on a new "geometrical model" of omnidirectional scatterers as spatially distributed uniformly on a two-dimensional hollow-disc (i.e., a thick ring) centered upon the mobile. By varying the hollow-disc’s thickness, this spatial density degenerates to the well-known uniform-ring or uniform-disc densities.
