BER Analysis of Digital Modulation Schemes for OFDM System
Abstract: The growth in the field of communication and the requirement of high-speed and secured data transmission are increasing day by day. Orthogonal frequency-division multiplexing modulation technique is a new technique which supports high-speed data transmission. It is a method of signal modulation that divides a high data rate modulating stream into several slowly modulated narrowband close-spaced subcarriers, and in this way, it is less sensitive to frequency-selective fading. The present …
