To achieve more accurate measurements of the mobile station (MS) location, it is possible to integrate many kinds of measurements. In this paper we proposed several hybrid methods that utilized time of arrival (TOA) at seven base stations (BSs) and the angle of arrival (AOA) information at the serving BS to give location estimation of the MS in non-line-of-sight (NLOS) environments. From the viewpoint...
A novel algorithm of iterative channel estimation and turbo decoding for pilot symbol assisted modulation (PSAM) is proposed. The proposed channel estimation is based on least squared fitting (LSF) theorem. Compared with the linear optimum MMSE (minimum mean square error) channel estimation, it doesn¡¦t require any channel characteristic like as fading rate or noise variance. We discuss the effect...
