A measurement of signal-to-noise ratio versus trackwidth from 128 µm to 4 µm
1987 Edition, Volume 23, September 1, 1987 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Bulk-erased tape noise will vary as the square root of the reproduce head trackwidth if the noise signal is uncorrelated across the track. Recent models of erased noise involve clusters of interacting particles that could be as large as...

Signal Recovery from Unlabeled Samples
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we study the recovery of a signal from a set of noisy linear projections (measurements), when such projections are unlabeled, that is, the correspondence between the measurements and the set of projection vectors (i.e.,...

Joint Measurement of Signal Parameters and ADC Transition Levels
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The estimation of the amplitudes and phases of the components of a periodic signal based on the sequence of its quantized samples is a typical problem in instrumentation and measurement. If the signal and noise properties are...

Measurement Technique to Emulate Signal Coupling Between Power Amplifiers
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A measurement technique to emulate coupling between power amplifiers (PAs) such as that in an antenna array is presented. The case that the technique aims to emulate is referred to as the target array. The technique provides emulation of the distorted...

Objective MIMO Measurement
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Over-the-air (OTA) measurements are the standardized methods to evaluate radio performance in wireless systems. Handling multiple input and multiple output (MIMO) situations in OTA measurements is critical for the fourth generation (4G) long-term-evolution (LTE) and upcoming...

Graph-Variate Signal Analysis
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Incorporating graphs in the analysis of multivariate signals is becoming a standard way to understand the interdependency of activity recorded at different sites. The new research frontier in this direction includes the important problem of how to...

Repeat-Accumulate Signal Codes
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

State-constrained signal codes directly encode modulation signals using signal processing filters, the coefficients of which are constrained over the rings of formal power series. Although the performance of signal codes is defined by these...

Signal Space Cognitive Cooperation
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this work, a new transmission scheme, signal space cognitive cooperation, is introduced by applying the idea of signal space diversity in an underlay spectrum sharing decode-and-forward multi-relay cooperative network. In the proposed structure, the secondary source...

Measurement and Analysis of Input-Signal Dependent Flicker Noise Modulation in Chopper Stabilized Instrumentation Amplifier
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents measurement results and an analysis of an input-signal dependent flicker noise modulation in chopper stabilized current balancing instrumentation amplifier. Although the chopping is well known and often used for its effectiveness in flicker...

Compressed Sensing based UWB Receiver using Signal-Matched Sparse Measurement Matrix
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a deterministic signal-matched sparse measurement matrix for ultra wide-band (UWB) systems. The proposed matrix is easy to implement and is computationally efficient as needed in a practical system. The proposed matrix captures higher...
