On Channel Estimation of OFDM-BPSK and -QPSK over Nakagami ...
To analyze the performance of OFDM-BPSK and -QPSK systems over Nakagami-m fading channel, we consider the total number of sub-carriers 400, the IFFT /FFT length is chosen to be 1024 by using Guard interval of length 256. 0 5 10 15 20 25 30 10-4 10-3 10-2 10-1 10 0 Channel SNR (db) BER BER Vs.SNR Using Nakagami-m fading channel for BPSK m =1 m=1.2...
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...

BER Performance of OFDM-BPSK over Nakagami Fading Channels Mukesh Kumar Mishra Department of Electronics and ... value of m is achieved to be 1.4 for Nakagami-m distribution, to estimate the fading channel. This interesting fact about ... Fig.1 BER vs. SNR for OFDM-BPSK system over Nakagami-m Fading Channel ....
Asymptotic CRB on SNR estimation of QPSK signals in low ...
A simple closed-form expression is derived for the low signal-to-noise ratio (SNR) asymptote of the Cramér-Rao bound (CRB) on the estimation of SNR for quarternary phase-shift-keying signals received over Nakagami-m fading channels with L branch equal gain diversity combining.
