Performance analysis of WPM‐based transmission with equalization‐aware bit loading

open access: yesETRI Journal, 2018
Wavelet packet modulation (WPM) is a multicarrier modulation (MCM) technique that has emerged as a potential alternative to the widely used orthogonal frequency‐division multiplexing (OFDM) method.

Minimum Bit-Error Rate Design for Space-Time Equalisation-Based Multiuser Detection

open access: yes, 2006
A novel minimum bit-error rate (MBER) space–time equalization (STE)-based multiuser detector (MUD) is proposed for multiple-receive-antenna-assisted space-division multiple-access systems. It is shown that the MBER-STE-aided MUD significantly outperforms

An Energy Efficiency Perspective on Training for Fading Channels

open access: yes, 2007
In this paper, the bit energy requirements of training-based transmission over block Rayleigh fading channels are studied. Pilot signals are employed to obtain the minimum mean-square-error (MMSE) estimate of the channel fading coefficients.

Minimum Mean Square Error Estimators for the Exponential SSALT Model

open access: yesInformatica, 2016
Summary: This paper presents minimum mean square error (MMSE) estimators for mean life and failure rate of Exponential distribution model based on failure censored step-stress accelerated life-testing (SSALT) data. The MMSE estimators are drived by revising the corresponding unbiased estimators in terms of mean square error (MSE).

Kernel Methods for Small Sample and Asymptotic Tail Inference for Dependent, Heterogeneous Data [PDF]

open access: yes
This paper considers tail shape inference techniques robust to substantial degrees of serial dependence and heterogeneity. We detail a new kernel estimator of the asymptotic variance and the exact small sample mean-squared-error, and a simple ...

Asynchronous Channel Training in Multi-Cell Massive MIMO

open access: yes, 2017
Pilot contamination has been regarded as the main bottleneck in time division duplexing (TDD) multi-cell massive multiple-input multiple-output (MIMO) systems. The pilot contamination problem cannot be addressed with large-scale antenna arrays.

Binary Estimator Selection Methods for Hearing Aids With a Remote Microphone

open access: yesIEEE Access
Using a high signal-to-noise ratio remote microphone (RM) with hearing aids (HAs) is advantageous for HA users. However, the benefit depends significantly on the properties of the wireless channel.
