Long Term Evolution is a new advancement in the era of cellu lar technology emerged in recent decade that can accommodate the features of quite efficient radio access with high peak data rates as well as high capacity for voice links. Actually it is a journey toward 4 th generation with the recent 2G and 3G network operators. This revolution is an improvement over GSM, EDGE G, WCDMA/UMTS, and HSPDA and then HSPA+ to fulfil the demand of high speed mobile networks. This paper primarily describes a comparison of Single Carr ier Frequency Division Multiple Access (SC - FDMA) and Orthogonal Frequency Division Multiple Access (OFD MA) multiple access techniques. This comparison is carried out for the selection of multiple access schemes for the implementation of L ong Term Evolution (LTE) systems. Also the advantages and disadvantages of SC - FDMA and OFDMA schemes are described. SC - FDMA is proved better than OFDMA in terms of Peak to average power ratio (PAPR).SCFDMA and OFDMA systems are modelled with MATLAB for PAPR analysis.
