Abstract

In this Paper, proposed OFDM system design is simulated using Matlab simulink toolbox. The digital modulation schemes such as M-PSK (M-ary Phase Shift Keying) and M-QAM (M-ary Quadrature Amplitude Modulation), which provide way of parallel transmission, are compared to analyze the BER performance of designed OFDM system. Mentioned schemes used in OFDM system can be selected on the basis of the requirement of power or spectrum efficiency and BER analysis. In wireless communication, concept of parallel transmission of symbols is applied to achieve high throughput and better transmission quality. OFDM is one of the techniques for parallel transmission. Keywords: Orthogonal Frequency Division Multiplexing (OFDM), Bit Error Rate (BER), Wireless communications.
