    Parameters influencing air interference in 4G WCDMA mobiles
    (2006) Priyatamkumar; Banakar, Dr.R.M.; Shankaranand, Dr.B.
    Air interference, high usability and global coverage are some of the research challenges associated with 4G mobile systems. In this paper we analyze the parameters influencing air interface in 4G WCDMA systems at the physical layer and Link layer. A system model is proposed to increase the coverage range without increasing the transmitter power but by enhancing the SNR at the receiver end. ©2006 IEEE.

    Antenna gain determination using a microwave CAD tool-HFSS
    (2008) Bojja Venkatakrishnan, B.V.; Srivatsan, R.; Raghavan, S.; Sriram Kumar, D.S.
    Antennas have been increasingly studied in recent years. Different antennas have been designed for different applications based on the characteristics of the receiving side. Antennas cannot be fabricated as such and then be studied on. This leads to waste of material and requires a lot of iterations until we get the final design. In order to study the characteristics of an antenna without fabricating it, we need a special tool called a "SIMULATOR TOOL". It can determine all possible characteristics of an antenna under test. In this paper we'll be simulate few of the antennas using HFSS simulator tool. © 2008 IEEE.
