dependence between random variables
hello forum. two (or more) random variables x and y are totally independent if their joint pdf can be factorized: f(x,y)=f(x)*f(y). Also E[g1(X)g2(Y)]=E[g1(X)]E[g2(Y)], correct? Why does the fact that any functions g1() and g2() make the variables independent, while E[X Y]=E[X]E[Y] makes them only uncorrelated... 16 May 2010 21:12

Equalization without a training sequence
I have seen many IEEE papers on what is now called Blind Equalization where a PBRS sequence is not needed for training. This is for muliple- channel (multivariable) problems. A colleague of mine says this is just academic rubbish and not used in practice. true or false and if true would there be any advantage? ... 17 May 2010 11:17
Filtering with MATLAB's ifftshift
The MATLAB fft is defined over the nonnegative time interval t = dt*(0:N-1); t = 0:dt:T-dt; t = linspace(0,T-dt,N); where dt = 1/Fs and T = N*dt is the temporal period (corresponding discrete time period is N) induced by ifft(fft(x)) When xb is defined over the "centered" bipolar time interval tb = t - d... 20 May 2010 14:58

Hi, I am experimenting with the feedforward linearization technique for a amplifier with a specified AM/AM, AM/PM response. Could someone help to shed some light on the advantage of linearization? At first, I thought linearization allows IBO to be decreased so one can operate closer to saturation. Then I came to me ... 20 May 2010 01:55
irrational numbers and periodic signals....
hello forum, in the continuous time domain, the sum of 2 sinusoids of different frequencies w1, w2, results in a periodic signal only if w1/w2 is a rational number. If w1 and w2 are integers or decimals with finite digits, then their sum is alway periodic (a finite decimal or an infinite periodic decimal can be... 18 May 2010 05:58
