In this paper, we derive for the first time an explicit expression for the stochastic Cramér-Rao lower bound (CRLB or CRB) of the DOA estimates from spatially and temporally correlated signals generated from noncircular sources. The new CRB is compared to those of circular temporally correlated and noncircular independent and identically distributed (iid) signals. It will be shown that the CRB obtained...
In this paper, we address the problem of data-aided (DA) and nondata-aided (NDA) per-antenna signal-to-noise ratio (SNR) estimation over wireless single-input multiple-output (SIMO) channels from linearly modulated signals. Under constant channels and additive white Gaussian noise (AWGN), we first derive the DA maximum-likelihood (ML) SNR estimator in closed-form expression. The performance of the...
