BER performance of OFDM-BPSK and-QPSK over Nakagami-m ...
In this paper, the performance of OFDM-BPSK and-QPSK system in Nakagami-m channel has been reported. Here our approach is based on decomposition of Nakagami random variable into orthogonal random variables with Gaussian distribution envelopes. Results have been presented to obtain optimum value of m based on BER and SNR.
 BER Performance of OFDM-BPSK and -QPSK Over Generalized ...
Nakagami-m channel has been reported to close to 10-2, whereas, in Generelaized Gamma fading channel, BER is reported to be around 10-4. It clearly shows the severity of fading present in Nakagami-m distribution and flexibilty of Generalized Gamma fading channel. Figure 3. BER vs. SNR for OFDM-BPSK System Figure 4. BER vs. SNR for OFDM-BPSK System...
Efficient BER Analysis of OFDM System over Nakagami-m ...
In this paper, we present an efficient technique for the BER of OFDM system over Nakagami–m fading channels, using well known characteristics function based analysis approach. The average BER expressed in terms of the higher transcendental function such as the confluent hyper geometric functions. Our numerical results show that depending on the number of channel taps, the BER performance may ......
