We prefer OFDM technique to achieve high data rates in mobile environment. The task of estimating the frequency response of the radio channel which the transmitted signal travels before reaching the receiver antenna is known as Channel Estimation. A dynamic estimation of channel is necessary before the demodulation of OFDM signals since the radio channel is frequency selective and time-variant ...

Cholinergic neurons of the brainstem olivary complex project to and inhibit outer hair cells (OHCs), refining acoustic sensitivity of the mammalian cochlea. In all vertebrate hair cells studied to date, cholinergic inhibition results from the combined action of ionotropic acetylcholine receptors and associated calcium-activated potassium channels. Although inhibition was thought to involve excl...

Differential space-time modulation (DSTM) for multiple antenna communication systems has been recently proposed for frequency-nonselective fading channels. In broadband multirate systems, frequency-selective fading may occur. In this paper, the DSTM in frequency-selective fading channels is considered. A linear equalizer for the DSTM is proposed over frequency-selective fading channels. Further...

In this paper a frequency offset estimation technique for Wireless Local Area and Wireless Metropolitan Area Networks is presented. For frequency offset estimation, we have applied a low-complexity frequency offset estimator for simple AWGN channels to fading channels for MIMO-OFDM systems. Simulation results have shown that the performance of the proposed estimator is better than the low compl...

in order to the enhancement of the quality of speech corrupted by additive noise, a speech enhancement method has been put forward based on the combination of spectral subtraction and binary masking. spectral subtraction is a powerful method for removing noise from speech and binary masking provides essential elements to be used in monaural speech segregation. in the proposed combined method, f...

Objectives: Autism Spectrum Disorder (ASD) is a group of neurodevelopment syndromes with impairments in social communications and restrictive or repetitive behaviors. Neurofeedback is a new method that may regulate neuro and metabolic function in brain. This study is semi-experimental, with pre and post test.  Methods: In 26 children with ASD, 40 sessions of Neurofeedback were done. Brain...

Long term evolution (LTE) of universal mobile telecommunications system (UMTS) is one of the most developed wireless broadband systems worldwide. Based on orthogonal frequency-division multiple access (OFDMA), it provides high-speed data packets access for various deployment scenarios. Link adaptation is a technique used in the LTE system in order to exploit the benefits of the frequency select...

This paper proposes the Asymmetric Double Gate Silicon Substrate HEMT (ADG-Si-HEMT) to study carrier concentration and intrinsic small signal parameters of InSb/AlInSb silicon wafer DG-HEMT device. The HEMTs work as a three-port system device is named when top bottom gates are biased with different gate voltages. position quasi-Fermi energy levels (Ef) used investigate modulation back-channel c...

The origin of the concept of the meridian system is closely connected with the treatment effects of acupuncture, and it serves as an empirical reference system in the clinical setting. Understanding the meridian channels would be a first step in enhancing the clinical efficacy of acupuncture treatment. To understand the relationship between the location of the disease and the sites of relevant ...
