## Re: Cyclic prefix concept in LTE

"Cyclic Prefix" is introduced to overcome ISI (intersymbol interference) and simplify the equalization problem in OFDM. It works by making the linear-convolution...

## Re: Eye opening calculation

Please attach a picture.One of many definitions for EyeOpening is "vertical amplitude of the blank-region without any waveforms passing through the blank-region"...

## Re: Invert Phase Response

For FIR filter with coefs C1 = = [b0, b1, b2] and Z-transform H1(z) = b0 + b1 z^-1 + b2 z^-2, reversing coefs gives filter C2 = [b2, b1, b0] with H2(z) = b2 + b1...

## Re: All digital PLL loop bandwidth

Yes. You should be able to simulate continuous-time-PLL using Simulink and discrete-time-PLL using C-code and compare the two thus checking if your conversion is...

## Re: All digital PLL loop bandwidth

Z-transform variable z = exp(j*w), where j*j = -1.w = 2*pi*f*Ts where f = analog-frequency and Ts = time-period of uniform-sampling.So f = Fs corresponds to w =...

## Re: Processing block size and matched filtering

If you know freq of incoming tone (some error is allowed) then you correlate (multiply & integrate) the incoming signal with sine & cosine (2 correlations)...
