This paper proposes a weighted total least squares approach based on both pseudorange and carrier phase measurements. The paper makes use of the weighted total least squares solution to solve the global positioning system (GPS) navigation equation determining the user position. The total least squares estimation considers both measurements vector and observable data matrix errors which common least...
Spectrum sensing plays a key role in enabling the cognitive radios access to vacant spectrum, since it helps avoid interference with the incumbent users. However there are not many studies that show the feasibility of the detectors and analyze their performance under real noise and interference conditions.
