Mitigation of Mobile Radio Parasitic Radiation Effects: A Review
Abstract: ABSTRACT In this paper, mitigation techniques useful for improving mobile radio systems power efficiency and decreasing electro-smog and specific absorption rate (SAR) induction, affecting human head and body, are presented. An analysis of main radiation effects from far field base stations and review of mitigation techniques for enhancing the efficiency of power transmission for mobile radio systems is shown, followed by an investigation of the complex radiation field components from …

Performance Analysis of OFDM System Using Non-conventional Transform and Non-conventional Mapping Schemes over Rayleigh Channel
Abstract: ABSTRACT High data rate wireless transmission is required to meet the rapidly increasing demands for mobile communications. Fast Fourier transform (FFT)-OFDM has drawn much attention due to its simple implementation and robustness against frequency-selective fading channels. Recently, the advantages of the discrete cosine transform (DCT)-based OFDM have come to the light. In this paper, performance of the conventional FFT-OFDM system is compared with non-conventional DCT-OFDM in terms of bit error …

Proposal to Use Cartography for Predicting the Urbanization as an Aid to Communication Network Planners
Abstract: ABSTRACT In this paper, a proposal has been made to incorporate the concept of urbanization level in the maps supplied to different vendors. This in turn would aid the network planners of the telecommunication, and cellular industry to plan the network, BTS site planning, cell size planning and efficient frequency planning also. All the advantages of incorporating urbanization level have also been well discussed. Keywords: DTM, Urbanization, GSM, Network, Planning
