Pilot-Based Time Domain SNR Estimation for Broadcasting OFDM Systems
The estimation of signal-to-noise ratio (SNR) is a major issue in wireless orthogonal frequency-division multiplexing (OFDM) system. In OFDM system, each frame starts with a preamble symbol that facilitates the SNR estimation. However, the performance of

Sensitivity and parameter-estimation precision for alternate LISA configurations [PDF]
We describe a simple framework to assess the LISA scientific performance (more specifically, its sensitivity and expected parameter-estimation precision for prescribed gravitational-wave signals) under the assumption of failure of one or two inter ...

Performance Enhancement of Decision Directed SNR Estimation by Correction Scheme of SNR Estimation Error [PDF]
In this paper, the SNR estimation error of Decision Directed SNR estimation method in AWGN is investigated, which uses samples received in reference decision region. In communication system receiver, when SNR estimation scheme using error vectors between ideal sample points and received sample points of reference region is adopted, the samples contain ...

Bioinspired auditory sound localisation for improving the signal to noise ratio of socially interactive robots [PDF]
In this paper we describe a bioinspired hybrid architecture for acoustic sound source localisation and tracking to increase the signal to noise ratio (SNR) between speaker and background sources for a socially interactive robot's speech recogniser system.

Improved SNR estimation for BPSK and QPSK signals
A novel non-data-aided SNR estimation technique for BPSK and QPSK modulations in complex additive white Gaussian noise (AWGN) is proposed. It uses the constant amplitude property of in-phase and quadrature components of these modulations to achieve an improved performance.

Non-Data-Aided Parameter Estimation in an Additive White Gaussian Noise Channel
Non-data-aided (NDA) parameter estimation is considered for binary-phase-shift-keying transmission in an additive white Gaussian noise channel. Cramer-Rao lower bounds (CRLBs) for signal amplitude, noise variance, channel reliability constant and bit ...

Perceptually Motivated Wavelet Packet Transform for Bioacoustic Signal Enhancement [PDF]
A significant and often unavoidable problem in bioacoustic signal processing is the presence of background noise due to an adverse recording environment. This paper proposes a new bioacoustic signal enhancement technique which can be used on a wide range
