Abstract

Dynamic spectrum access systems will need to simultaneously share the same frequency band with existing systems, particularly in initial deployments. In the case of directional systems, this can be accomplished through spatialdivision-multiple-access (SDMA), by taking advantage of the directionality of the antennas involved and the location of the transmit and receive antennas to avoid interference. This paper describes a methodology for determining the region in which transmit and receive antennas can be located to avoid interference. An example involving a satellite downlink antenna and a broadband wireless access system using directional antennas is presented.
