Investigating 802.11a Wireless Standard for High Speed Network Using Different Modulation Techniques
In an OFDM system, typical sub-carrier modulation schemes include Binary Phase Shift Keying (BPSK) Quadrate Phase Shift Keying (QPSK), and Quadrature Amplitude Modulation (QAM). High level of modulation is used in order to increase the data rate of the OFDM system. In this paper, the analysis of high level of modulations techniques such as BPSK, QPSK, 8PSK, 16PSK, QAM using MATLAB SIMULINK on OFDM system is presented. Here AWGN channels have been used for analysis purpose and their effect on BER for high data rates and Signal-to-Noise Ratio (SNR) to be improved in a noisy channel at the cost of maximum data transmission capacity have been presented.
