It is pdf apparent that uncertainties are present in both antenna arrays as well as in the target models. Therefore, a major thrust of this thesis is also directed toward robust parameter estimation of moving sources. Consequently, new techniques have been developed to estimate the source parameters.

Because of the increasing need to accommodate more users in the current available spectrum, antenna array is the modern approach being considered to estimate direction of arrival (doa track moving sources and parrot signal detection. With the advances in semiconductor and antenna technologies it becomes very attractive to develop new techniques to enhance the capabilities of antenna array in many areas such as radar systems, sonar, ultrasound imaging systems, mobile communications, etc. Most of the earlier works were concentrated only in estimating or tracking the angle of arrival of the emitting source by using either a subspace based technique or a kalman type algorithm. This has a shortcoming, especially for rapidly moving sources. In this thesis, methods have been proposed to estimate both the angle of arrival and velocity of moving sources. In particular, we focus on a nonparametric approach to evaluate both the angle of arrival and angular velocity of a moving source using planar array. The combined doa and angular velocity estimation algorithm is defined as doav in this thesis.
calibration prior to startup. Two methods of performing auto-calibration of an adaptive antenna for mobile telecommunications are proposed. The weighting is assumed to be implemented in hardware. The first method proposed is a closed-loop, lms-like algorithm, whereas the second takes on a tracking approach. Simulations show that the two methods are able to maintain a good performance for realistic temperature drifts. PhD Thesis Defense of Webert Montlouis. Title: Robust doav estimation and Tracking, techniques for moving sources, date : november 18, 2004. Abstract, early study shows that the application of smart antennas can increase system capacity and performance in mobile communication.
The channel estimate obtained utilizing the pulse shaping information can be further improved by projection onto a spatially parameterized subset. The projection is performed in a spectrum norm sense, and has been investigated by means of add simulations. By utilizing the channel estimation method in a multidimensional mlse (maximum likelihood sequence estimator) detector, a significantly improved bit-error rate can be obtained. Measurements of an adaptive dcs-1800 (Digital Communication System) base station antenna, used in uplink only, are then presented and analyzed. Both laboratory measurements and outdoor field trials have been performed. The antenna is improving the C/I (carrier-to-interference) ratio by more than. Calculations based on measured data, assuming downlink performance equal to that of the uplink, predict six times improved spectral efficiency gain as compared to present base station systems. The performance degradation of adaptive antennas due to inaccuracies in weights and quantization in A/D converters is also investigated. An analytical expression for the variance of the weight quantization error is derived for the log-phase-amplitude weighting technique and is used to calculate the output sinr of the adaptive antenna.

In order to perform equalization, a good channel estimate from the mobile to the base-station is required. In this thesis, a method for essay channel estimation for multi-user digital communication is presented. The method utilizes the knowledge of the pulse shaping performed in the transmitter and in the receiver. The method is based on approximating the pulse shaping in the transmitter and the known filtering at the receiver with a set of pulse shaping functions sampled at different time instants. The modeling is illustrated with the pulse shaping function used in d-amps (IS-54). The method can be used for single user channel estimation, but is especially useful for multi-user channel estimation since it is economic with respect to the number of parameters to be estimated. This is shown in a multi-user channel estimation example.
