RSS estimatorA Two-Stage Plug-in Bandwidth Selection and Its Implementation for Covariance Estimation
White Paper This paper suggests an alternative approach that estimates an unknown quantity in the optimal bandwidth for the HAC estimator (called normalized curvature) using a general class of kernels, and derives the optimal bandwidth that minimizes the... [11 Jul 2008]
A Bayesian Approach to Bandwidth Selection for Multivariate Kernel Regression With an Application to State-Price Density Estimation
White Paper It is generally accepted that the performance of a kernel regression estimator largely depends on the choice of bandwidth rather than the kernel function. Multivariate kernel regression is an important tool for investigating the relationship... [08 Jul 2008]
Synchronization in Interleaved OFDMA Systems
White Paper This paper investigates the base station receiver signal structure, and a structure based estimator is proposed for simultaneously estimating multiple users' carrier frequency offsets. Orthogonal Frequency Division Multiple Access (OFDMA) as a new... [03 Jul 2008]
ICI Cancellation Based Channel Estimation for OFDM Systems
White Paper This paper proposes a novel frequency-domain channel estimator, which mitigates the effects of ICI by jointly finding the frequency offset and channel frequency response (CFR). Orthogonal Frequency Division Multiplexing OFDM), which is a... [11 Apr 2008]
Replica Analysis of Large-System CDMA
White Paper In the latter case, a conditional mean estimator is first applied to separate the users and it is found that the resulting single-user channel for every user is equivalent to a Gaussian channel. This paper presents some new results on large-system... [10 Apr 2008]
