Dirty Paper Coding is practical?

We can easily find the good theoretic rate bound of dirty paper coding. I am wondering whether it's a practical coding？ Can any conventional coding, such as superposition coding, can beat it? Thanks,

Does anyone know the latest reports on spectrum of quantization error?

As I know, there is a good paper talking about this, B. R. Bennett, 'Spectra of Quantized Signal' 1948. I am wondering there is newer report on this topic for the signal with colored spectrum?...

How can I integrate the degenerate multidimensional Gaussian?

For simplicity, what is the explicit expression of integral (3 dimension for example), \int_{x1} \int_{x2} \int{x3} exp(-(k1*x1+k2*x2+k3*x3)^2) dx1 dx2 dx3 The attached figure shows the integral...

Is there any analytic expression describing how a histogram is close to a PDF?

In many case we approximate histogram of a data set as the probability density function. Can we quantize the difference between the PDF and the histogram? Is there analytic expression to describe...

Is each tap of ITU channel model necessary to be Rayleigh/Rician distributed?

Hi, From the introduction of the ITU models, I find the spectrum for each tap is specified, e.g. classic, flat. Are there any specification on the distribution for each tap? In other words, the...

Does the Wiener Filter work in arbitrary signal and additive noise?

Wiener filter is a MMSE estimator. The thing I am concerned about is whether it works in any type of additive noise? Does the expression of WF $H_{wf}(f)={S_{xy}(f)}/{S_{xx}(f)+N(f)}$ fits for...

How does the sampling period affect the spectrum of the sampled white Gaussian process?

n(t) is white Gaussian process. T1 and T2 are the periods at which n(t) is sampled, N1=n(m \cdot T1), N2=n(m \cdot T2). S1(f) and S2(f) are the spectrum of N1 and N2 respectively. What is the...

What are the linear estimators for memory source (signal with colored spectrum)?

MMSE is a widely used linear estimator for i.i.d signal. If the realization of signals at different time instances are not independent, can MMSE be used or not? Does it have to do with the...
