Introduction to Mediumband Wireless Communication

The multipath is unavoidable in radio frequency (RF) wireless communication, and affects almost every element of the communication systems.The impact of multipath on the received signal depends on whether the delay spread (i.e., spread of time delays associated with different multipath components) is large or small relative to the symbol period of

LORETA current source density for duration mismatch negativity and neuropsychological assessment in early schizophrenia.

INTRODUCTION: Patients with schizophrenia elicit cognitive decline from the early phase of the illness.Mismatch negativity (MMN) has been shown to be associated with cognitive function.We investigated the current source density of duration mismatch negativity (dMMN), by using low-resolution brain electromagnetic tomography (LORETA), and velgen vff

The noise absorption prediction of a combined and independent absorber under different conditions and at different frequencies, using the new Engineering Noise Control Software (ENC)

Noise is one of the most harmful factors in the work environment, which is very important to control.There are various techniques to achieve this goal.One of the most important of them is the use of noise absorbers.Absorbent materials are often used to counteract the effects of reflected noise from hard surfaces and reduce their level.This is an ex
