  Abstract

In this paper, we propose an OFDM scheme to increase the BER performance. The proposed OFDM scheme makes the baseband OFDM signal by using the oversampled OFDM Signal values which are obtained by inserting N(=2k) zeros and carrying out 2N point IFFT. In the demodulation part, the sampling operation for AID conversion is earned out with the 2 times high sampling speed 2 N point FFT is earned out for the data demodulation. In this paper, we show, with the mathematical method and the computer simulation, that the SNR of the proposed OFDM scheme is 3 dB higher than that of the conventional OFDM in the same AWGN channel conditions given.
