Request for papers
Dear forum members!!!
I need a number of papers mainl from IEEE but also from some other sources. Unfortunately I do not have access to these bases (electronic access) and therefore I am not able to obtain them now. If you can do this or, at least, know where it is possible...
You should realize, that the completely determined wave, such as s(t) = Acos(wt+phi) doesn't contain any useful information, because all the parameters of the function given are determined and exact, therefore there is no need of transmitting such signal, as no new information will be obtained...
Normalization is a basic statistical operation. It's used to scale heterogeneous sets of data, so that they could be compared relevantly. Also normalization facilitates defining thresholds in different threshold algorithms. Finally, the data range decreases and is confined to [0;1] (see 1) )...
physical convolution
Convolution is widely used in various filtration techniques. If the input signal is s(t) and the filter has impulse response h(t), then the output signal is evaluated by means of convolution of the input one and the impulse response. This is a, so-called, linear...
Re: Z-transform
Also the books by B. Sklar "Digital Communications" and Aificher, Djervis "Digital Signal Processing" also contain a lot of useful information relatively Z-transform. In general, this knowledge are available in all books on DSP and DC.
With respect,
Dmitry
I'm not completely sure, because I've never come across such expression, but I think that Kolmogorov fundamental axioms are meant here. They are rather evident and clear and may be found in any textbook on probability theory.
With respect,

shannon limit 1.6
Shannon limit: Eb/N0 = -1.6 dB, where Eb - a bit enegy, N0 - one-sided power spectral density of noise, which is usually considered to be Gaussian.
This expression means, that if Eb/N0<-1.6 dB there are definitely no any noise combating codes at all, which can provide...
Re: hi frndz
My dear friend: at first only Bernard Sklar "Digital Communications - Fundamentals and Applications". This book is undoubtedly the best one, devoted to DC, however you should have some knoledge from mathematics and DSP to understand it. Also, many Internet resources on DSP are...
Re: HETERODYNE DETECTORS
As for me, I quite agree with A.Anand Srinivasan: heterodyning is used for tranfering the signal from one carrier frequence to another. This may be caused by the features of system bandwidth, necessity to get rid of noise and so on. After recept a signal may be...
viterbi decoder(5/6)
Viterbi decoding is the maximum-likelihgood decoding algorithm, mainly used in systems with Convolution(al) codes. The latter means, that it's absolutely exact, but not numerical algorithms. Due to its existense convolutional codes are very spread now. Of course, Viterbi...
Re: Orth in time and freq
Orthogonality of 2 signals (functions) means, as you've written, that their inner product is equal to zero. Your formula is almost right, but the complex conjugate sign must be considered:
I = int(x1•x2*) = 0. If this is true, 2 functions are orthogonal.
It's...
Regarding the decimation opoeration itself without any particular link to decimation filter, it's used in constructing filter banks, especially the most widespread dyadic filter banks. It's very actual in discrete wavelet transform (DWT), empirical mode decomposition (EMD), singular spectrum...
Re: Conferences on DSP
Dear friends!!!
I'm waiting for your suggestions. If you are aware of any conferences on DSP, please, let me know.
Thank in advance
With respect,
Dmitrij
Re: Springer
Thank you all for your references, but still, in spite of this, I urgently need the access to Springer Base of Books.
If anyone has the opportunity to download for me some books from Springer, let me know, please.
Thanks, in advance.
With respect,
Dmitrij
