Abstract

OFDM is turning into the chosen modulation technique for wireless communication to reduce multipath fading effects and to provide massive data rates. OFDM is a multicarrier transmission system that utilizes the method of ripping smaller subcarriers of frequencies to agitate multipath drawback. Multipath distortion and Frequency interference are decreased through this system. OFDM has been accustomed develop the capability of CDMA networks and fulfils the wireless access technique for 4G networks. OFDM is meant to attain during a superior method just in that matter of frequency selective fading and narrowband interference. OFDM cuts the extent of interference in signal broadcasting .In this paper, we evaluated the performance of OFDM at different modulation techniques through BPSK,QPSK,16 QAM and 64 QAM and plot the graph between SNR and BER.The 64 QAM has the highest bit error rate and 64 QAM has the lowest bit error rate.

Key Words

BPSK; QPSK;16 QAM;64 QAM; SNR and BER.
