Estimating each path's angle of arrival (AOA) and propagation delay is necessary for several applications such as mobile localisation for emergency services and advanced handover schemes. In conventional JADE methods, the channel impulse response is estimated first from the received samples and then this impulse response is used to estimate AOAs and time delays of the multiple paths. We propose a Bayesian approach for joint AOA and time delay estimation of fading multipath signals in symmetric a-stable noise. Approximating /spl alpha/-stable noise by Gaussian mixtures, we derive a posterior probability density for the AOAs, time delays and the fade amplitudes given the received samples and the model order (number of multipaths). This posterior probability is then used with the Metropolis-Hasting algorithm to derive the samples for the AOAs, time delays and the fade amplitudes. Unlike the conventional subspace-based methods, this algorithm can be used with significantly lower number of samples.","PeriodicalId":365086,"journal":{"name":"1999 2nd IEEE Workshop on Signal Processing Advances in Wireless Communications (Cat.

Pilot symbol-assisted channel estimation has been adopted in the development of the third-generation wideband CDMA mobile communication system. However, the performance of the pilot symbol-assisted channel estimation is limited in a fast fading environment because only a few pilot symbols are inserted in each frame of received data in the third-generation wideband CDMA system. In this paper, a blind channel identification method is proposed based upon the Cross-Relation Method of Xu, Liu, Tong, and Kailath, in order to reduce the need for pilot symbols in coherent detection. First, an equivalent time-invariant single-input multi-output system is created for the de-spreaded signals through employing multiple antennas at receiver site. Second, the Cross-Relation Method is applied to the equivalent linear time-invariant single-input multi-output-channel model to blindly identify the channel. Simulations are performed to evaluate the blind channel identification method's applicability to third-generation wideband CDMA.","PeriodicalId":365086,"journal":{"name":"1999 2nd IEEE Workshop on Signal Processing Advances in Wireless Communications (Cat.
