  • Sep 2016
This paper examines the probability of the bit error rate (BER) and the spectral efficiency of the Orthogonal Frequency Division Multiplexing (OFDM) system and introduces the performance enhancement of using adaptive modulation in the system. Best modulation scheme according to higher data rates is investigated on the basis of channel quality indic...

... to the OFDM modulation, the OFDM demodulation can be achieved by using FFT instead of a bank of parallel correlators and by using a sampler with sampling rate , as shown in figure3 [16]. The whole OFDM system that is implemented by using IFFT/FFT can be shown in Figure 4. ...
