During the Digital Signal Processing sessions, a novel method of communication with an efficient use of the bandwidth was tried out in Matlab® and the results of the same were presented in ‘Sri Veknateswara College of Engineering’. During the summer internship at AU-KBC Research center, a Simulink® model of the popular 802. 11b standard was implemented for analysis and further research. In the current semester, I am doing ground work in the concepts of OFDM, MC_CDMA to gain more hold on these fields For my B. E project, I have decided to concentrate on my other area of interest viz. Wireless Communications. I am attempting to evolve a Optimal OFDM Design for Time–Frequency Dispersive Channels. Transmission over wireless channels is subject to time dispersion due to multipath propagation as well as frequency dispersion due to the Doppler effect. Standard orthogonal frequencydivision multiplexing (OFDM) systems using a guard-time interval or cyclic prefix combat intersymbol interference (ISI), but provide no protection against interchannel interference (ICI). This drawback has led to the introduction of pulse-shaping OFDM systems.
