In this paper, a joint delay/AOA/carrier estimator for
long code CDMA systems is developed. Channel parameter estimation
is useful in space-time processing systems and wireless location
systems that employ hybrid AOA/TOA technology. The estimator
makes use of a certain antenna array element setup organized
especially for the estimating process. The estimator incorporates
the use of the ESPRIT method to estimate the delays, AOAs
and carrier frequencies of each user and pairs the estimated parameters
automatically. It also avoids the computational burden
of a matching, or pairing, procedure and does not require the use
of a Fourier transform to aid the estimation of the delays. Further,
the algorithm performs the estimation directly without the need
of searching over a specified range to estimate any of the parameters.
Simulations are presented to show the performance of the
estimator.
