Abstract

In this paper we propose two data-record based criteria for the selection of an auxiliary-vector (AV) estimator from the sequence of AV estimators of the minimum variance distortionless response (MVDR) filter. The first criterion maximizes the estimated J-divergence of the bit-conditioned AV filter-output distributions, while the second criterion minimizes the cross-validated sample average variance of the AV-filter output. The developments in this paper are presented in the context of joint space-time direct-sequence code-division multiple-access (DS/CDMA) signal detection.
