Performance Improvement of Multi-UserMC-CDMA system Using Discrete Hartly Transform Mapper [PDF]
Future wireless communication systems must be able to accommodate a large number of users and simultaneously to provide the high data rates at the required quality of service. In this paper a method is proposed to perform the N-Discrete Hartley Transform

Dynamic Updating of Cognitive Maps via Traces of Experience in the Subiculum. [PDF]
ABSTRACT In the classical view of hippocampal function, the subiculum is assigned the role of the output layer. In spatial paradigms, some subiculum neurons manifest as so‐called boundary vector cells (BVCs), firing in response to boundaries at specific allocentric directions and distances.

A new type of modulation has been developed - Hartley amplitude modulation(AMH), which is distinguished by the presence of two orthogonal components of the amplitude- modulated signal, which allows increasing the efficiency of AMX up to 90 ...

Hippocampal-Prelimbic Coupling During Context-Dependent Extinction Retrieval in Rats. [PDF]
ABSTRACT After fear conditioning, repeated presentation of the conditioned stimulus (CS) alone produces a context‐dependent extinction of learned fear. The hippocampus has a critical role in this process, but the mechanism by which contextual information encoded by the hippocampus leads to fear suppression is unknown.

The Effect of EMI Generated from Spread-Spectrum-Modulated SiC-Based Buck Converter on the G3-PLC Channel [PDF]
Power line communication (PLC) is increasingly emerging as an important communication technology for the smart-grid environment. As PLC systems use the existing infrastructure, they are always exposed to conducted electromagnetic interference (EMI) from ...

Investigating Cortical Responses to Noise-Vocoded Speech in Children with Normal Hearing Using Functional Near-Infrared Spectroscopy (fNIRS) [PDF]
Whilst functional neuroimaging has been used to investigate cortical processing of degraded speech in adults, much less is known about how these signals are processed in children. An enhanced understanding of cortical correlates of poor speech perception

Low-PAPR Asymmetrically Clipped Optical OFDM for Intensity-Modulation/Direct-Detection Systems
In this paper, we propose a discrete Hartley transform (DHT)-spread technique for peak-to-average power ratio (PAPR) reduction in a DHT-based asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) system.

Bispectrum Analysis of Motor Current Signals for Fault Diagnosis of Reciprocating Compressors [PDF]
The induction motor is the most common driver in industry and has been previously proposed as a means of inferring the condition of an entire equipment train, predominantly through the measurement and processing of power supply parameters.
