This paper analysis the performances of a single antenna handheld receiver in detecting a signal in a Rayleigh multipath fading environment. If the antenna is spatially fixed during the time interval that the signal is sampled then signal coherency is maintained. However, the signal will be subject to statistically large fading losses. The alternative is to spatially translate the antenna along some...
In this paper, a new method for AOA estimation, based on the synthetic ESPRIT algorithm is described and tested with actual CDMA signals. Physical size constraints of handheld devices typically exclude the possibility of using multiple antennas. To overcome this limitation, antenna array can be synthesized by physically moving a single antenna in an arbitrary trajectory while collecting a snapshot...
This paper describes a hybrid AOA/TODA mobile station (MS) location estimation method based on the CDMA wireless communications signals. The method utilized estimates the angle of arrival (AOA) and time difference of arrival (TDOA) of downlink pilot channel. In this paper, signal parameter estimations including AOA and TDOA, and position estimation challenges in real wireless communications systems...
