Cognitive positioning system (CPS) that accomplishes precision adaptation, the realization of location awareness in cognitive radios. It empowers the client or wireless device itself to change situating accuracy adaptively. The proposed CPS is made out of two modes; bandwidth determination and enhanced dynamic spectrum management (EDSM). For both additive white Gaussian noise (AWGN) and multipath channels, Bandwidth assurance conditions are inferred through Cramer-Rao Lower Bound (CRLB). An EDSM framework giving the optimum accessible transmission capacity to the CPS is proposed.
