Figure 8 shows the results of the simulation for the transmission of 40 kb at several different values of Eb/ N0 and how it compares with theory. The result is acceptable and theoretical is similar to simulation. Thanks for visiting! Then BERTool creates another listing in the data viewer. More about the author

You can use confidence intervals to gauge the accuracy of the error rates that your simulation produces; the larger the confidence interval, the less accurate the computed error rate.As an example, Figure 4 shows the amplitude spectrum of the BFSK signal when m0(t) and m1(t) are periodic pulse trains.

This filter is often a square-root raised cosine filter, but you can also use a Butterworth, Bessel, Chebyshev type 1 or 2, elliptic, or more general FIR or IIR filter. for jj = 1:length(snr) reset(hErrorCalc) hChan.SNR = snr(jj); % Assign Channel SNR ynoisy(:,jj) = step(hChan,real(y)); % Add AWGN z(:,jj) = step(h2,complex(ynoisy(:,jj))); % Demodulate. % Compute symbol error rate from simulation.

Continuous phase FSK is not same as classical FSK. Figure 6 shows the results of the simulation for the transmission of 40 kb at different values of Eb/N0 and how it compares with theory. The word keyed' suggests that the message is of the on-off' variety, such as one (historically) generated by a binary sequence (Fig. 1).2 Continue on Page 2 Page Title The transmitter M Ary Fsk Modulation A common approach is to start with an augmented binary pseudonoise (PN) sequence of total length (log2M)ML.
The part of that example that creates the plot uses the semilogy function to produce a logarithmic scale on the vertical axis and a linear scale on the horizontal axis.Other examples The MATLAB function simulates the communication system whose performance you want to study. BERTool opens the BER Figure window after it has at least one data set to display, so you do not see the BER Figure window when you first open BERTool. http://onlinetvsoftware.net/bit-error/bit-rate-and-bit-error-rate.php After you instruct BERTool to generate one or more BER data sets, they appear in the data viewer.

This channel can include multipath fading effects, phase shifts, amplifier nonlinearities, quantization, and additional filtering, but it must not include noise.
