BER-Tool:
Hy, I am using the BER-Tool (Bit-Errorrate-Tool) in Matlab. When I simulate with a QPSK-Modulation and an AWGN-Channel there is difference between the simulated BER and the theoretical-exact BER. The difference is about factor 100 with Eb/No = 10 dB. But the two curves should be the same in ideal simulation, shouldn... 9 Jun 2010 03:10

multivariate binary logistic regression
FYI For anyone who has looked at these old post's as a guide for logistic regression in matlab (using glmfit). I found the glm function in R to handle categorical variables much better than glmfit in matlab. So if you are looking to do a quick logistic regression analysis, and you have categorical predictors, I would r... 9 Jun 2010 03:10

Modulation transfer function
Hello, I need to compute modulation transfer function from Zernike polynomials. Can you guys help me with that? Also when I compute MTF from Zernike polynomials for a number of eyes do I have to include the standard deviation of all those or just means of the polynomials. Thanks in advance, Krupa ... 9 Jun 2010 03:10

hi all i am working on a project .which is basically as follows---- I/p=105.078 to 109.765 MHz (OQPSK) and to convert this into o/p =965 to 1265MHz The solution for this is--- I/p----->mixer------>bpf------>o/p Now my problem is that i am not able to design mixer for this system in matlab/simulink . i... 9 Jun 2010 03:10

Plotting multiple figures
Hello This is Ronald. I need to plot several earthquake records in a single figure. I could use subplot but I do not want that. These records were from the same earthquake and recorded at different distances. By plotting them according to the epicentral distance I can read better rather than using subplot. I also w... 9 Jun 2010 18:41
