Optimal Quadratic-Form Estimator of the Variance of the Sample Mean
A classical problem of stochastic simulation is how to estimate the variance of the sample mean of dependent but stationary outputs. Many variance estimators, such as the batch me...

Replicated batch means for steady-state simulations with initial transients
We provide asymptotic expressions for the expected value and variance of the replicated batch means variance estimator when the stochastic process being simulated has an additive ...

Blind Carrier Frequency Offset Estimators Based on Variance for OFDM Systems
Abstract—Carrier Frequency Offset (CFO) estimation is critical in practical orthogonal frequency-division multiplexing (OFDM) systems. In this paper, we propose two novel blind C...
