rxsig = txsig*exp(1i*pi/180); % Static phase offset of 1 degree % Step 5. Reply candy July 24, 2012 at 11:17 am Dear Krishnan, Thank you so much for your help! Simulate 4-PAM (k = 2,M = 4). The Number of bits value prevents the simulation from running too long, especially at large values of Eb/N0. have a peek at these guys
Reply Krishna Sankar March 30, 2010 at 4:12 am @vj1892: Thanks Reply amit March 23, 2010 at 11:43 pm Hi, Can anyone help me in my project!!! Training courses Online - RF and Wireless Essentials for Engineers This on-line course enables you to quickly get up-to-speed & understand key concepts of modern radio frequency, RF & wireless communications Dunning Encoding and decoding for minimization of message symbol error rates in linear block codes IEEE Trans. SNR(dB) is used.
A more general way of measuring the number of bit errors is the Levenshtein distance. Reply Faisal November 11, 2009 at 2:20 am I am working on an adaptive modulation model on Simulink. I think that this result is not suitable with the fact that when BER will be increased to 1 when distance increased from 0 to infinite. The division by 20 is required to convert dB into voltage".
Hope to do so Reply anne na February 4, 2010 at 2:24 pm hi, I would like to demodulate QPSK but using soft decision. Reply Greg January 16, 2012 at 12:30 am I am having problems simulating the BER vs SNR curve for the binary on-off keying modulation.

The path loss depends on the square of the carrier frequency and square of the distance in free space. Reply Ozgeee December 26, 2012 at 3:37 am First of all, congratulations for this helpful and nice explanation.
This can be directly translated into the number of errors that occur in a string of a stated number of bits.

Your cache administrator is webmaster. The BER results obtained using Matlab/Octave simulation scripts show good agreement with the derived theoretical results. The energy per bit, Eb, can be determined by dividing the carrier power by the bit rate and is a measure of energy with the dimensions of Joules. http://onlinetvsoftware.net/bit-error/bit-error-rate-data-rate.php The function returns the bit error rate (or, in the case of DQPSK modulation, an upper bound on the bit error rate).Example: Using the Semianalytic TechniqueThe example below illustrates the procedure
xpecting fruitful reply. Bit Error Rate Testing noisyVec = step(comm.ErrorRate,code,codenoisy); decodedVec = step(comm.ErrorRate,msg,newmsg); disp(['Error rate in the received code: ',num2str(noisyVec(1))]) disp(['Error rate after decoding: ',num2str(decodedVec(1))])The output is below. Reply Krishna Sankar March 28, 2010 at 1:51 pm @amit: In AWGN there is no difference between using BER for BPSK and BER for BPSK using OFDM.
Thank you very much. i.e. Hence we model as two randn() variables each with variance 1/2. Bit Error Rate Tester Agilent I think that problem occurred at SNR or BER.
