one of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. the cars intensify greenhouse gas emission in civic centers. one approach to reduce the emission is replacing the cars by plug-in electric vehicles (pevs). in spite of reducing the emission, pevs have some adverse effect on electric distribution networks. technical challenges such as load and...

Multi-carrier modulation (MCM) techniques are used for high bit rate data transmission in radio transmission systems. The main scope of this work includes understanding a multi-carrier modulation system and setting up a simulation environment for such a system as applied in the case of Asymmetric Digital Subscriber Loop (ADSL) system and Orthogonal Frequency Division Multiplex (OFDM) system. Th...

This paper proposes a Multi-Code Multi-Carrier CDMA, best suited for multi-rate services using multicode schemes and multi-carrier services used for high rate transmission as required for the Universal Telecommunication Mobile Systems (UMTS) Long Term Evolution (LTE). The system performance has been analyzed and evaluated by means of signal-to-noise plus interference ratio and bit error rate un...

From the fourth generation (4G) of cellular systems onward, wireless personal devices (WPDs) support multi-input multi-output (MIMO) communication. However, impact MIMO communication on electromagnetic field (EMF) WPD users has yet to be fully understood and analyzed at system level. In this paper, we first provide a generic model for assessing individual exposure dose multi-antenna in multi-us...

The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...

In this paper, density evolution-based construction methods to design good polar codes on impulsive noise channels for single-carrier and multi-carrier systems are proposed and evaluated. For a single-carrier system, the tight bound of the block error probability (BLEP) is derived by applying density evolution and the performance of the proposed construction methods are compared. For the multi-...

In this paper, a type of multi-carrier direct sequence code division multiple access (MC-DS-CDMA) system which uses frequency spread coding is proposed and investigated for the down-link. An MC-DS-CDMA system is a combined system of CDMA and multi-carrier modulation. This system is often categorized as a “serial to parallel (S/P) type” system because serial to parallel converted data symbols ar...

A new wireless communication system denoted as Multi-Code Multi-Carrier CDMA (MC-MC CDMA), which is the combination of Multi-Code CDMA and Multi-Carrier CDMA, is analyzed in this paper. This system can satisfy multi-rate services using multi-code schemes and muti-carrier services used for high rate transmission. The system is evaluated using Traveling Wave Tube Amplifier (TWTA). This type of am...
