Let y = Hx be your system equation where x is the input and y is the output.
If you have inv(H), then your system equation is easily solved by doing x = inv(H)y. However, we cannot have inv(H) directly in many of the real applications. That is where the pseudo inverse comes from.
Although you...
From MMSE sense, you can induce the following relationship.
E[|WY - X|^2] ==> E[|WY - X|Y'] = 0 ==> WE[YY'] - E[XY'] = 0 ==> W = E[XY']/E[YY']
Here, E[XY'] is the cross-correlation, while E[YY'] is the auto-correlation.
So, E[XY'] = XX'H + XN' and E[YY'] = XX'HH' + XHN' + X'H'N + NN'
Since X...
ML is based on that all symbols are equally likely. It is nothing to do with a priori probability, which is used for MAP. However, if the priori probabilities are the same among symbols, then ML = MAP.
Zero forcing literally forces ISI to be zero. In other words, if H(z) is the channel...
Since random jitter is unbounded, rms is the effective way to represent it. If you want the random jitter in pk-pk term, you need to use a scaling factor for a specified BER. Otherwise, you cannot get the pk-pk value out of rms.
If you got the phase noise, saying N, then your rms jitter in...
Re: VCO Duty cycle
The duty cycle variation is another term called DCD(Duty Cycle Distortion) jitter. Since DCD is bounded, it is a kind of DJ(deterministic jitter). In deed, DJ can be decomposed in to ISI, DDJ, DCD and PJ(periodic jitter).
As you may know, jitter from VCO output is unbounded...
