Abstract

Escalating demand of higher data rate in progressive generations for wireless environment involve work towards modification of modulation schemes over air interface. Beginning from TDMA/FDMA/CDMA based 2nd generation to highly complicated Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), Interleaved FDMA (IFDMA) and Multi-carrier CDMA (MC-CDMA) which are gaining attention for 4G networks. OFDMA based WiMax standard and MC-CDMA based proposed IEEE 802.20 standards are evaluated for next generation. The paper presents analysis of performance of proposed modulation schemes for the next generation wireless communication i.e. OFDM and MC-CDMA. The paper is acquainted with comparison of OFDM and MC-CDMA for indoor to outdoor and vehicular channels. The simulation parameters considered are: guard time interval, symbol duration, sampling rate and number of data subcarriers. Performance based on various digital modulation schemes can also be associated with time varying channels.
