It is very good question. Usually to decide which distribution should be used we must conduct an experiment (in fact, scientists did it for us). Many phenomenons has a Gaussian distribution because of Central Limit Theory, i.e. given phenomenon (e.g thermal noise) is a compound of many principle...
Receiver calculates inner products of received signal with each basis signal. For orthogonal signals inner product is equal 0. It is the first method (called correlation receiver), the second one is a bank of matched filters (filters which are matched for each basis signal). In fact both methods...
Hi,
I know there are two Haykin's communication books: "Communication Systems" (I have 3 ed) and "An Introduction to Analog and Digital Communications". Could You tell me what are the differences between them? Is it worth to buy latter one?
Few days ago a book related to the topic was published (Cambridge Press). Its title is "Software Receiver Design: Build Your Own Digital Communication System in Five Easy Steps". Unfortunately i haven't read it yet because I ordered it two days ago and I get it for a few days.
Software Receiver...
Authors use H(e^jw) to emphasize that a frequency response (magnitude and phase) is periodic with a period 2pi. This notation is adequate for discrete-time systems.
Hi
There is no another explanation besides the fact that EM wave has many different ways in which it can reach a receiver antenna. Arrival time depends on the path which EM wave must travel, and because there is many such paths you have many copies of original signal. That's all.

Well, I think You should install Octave ver. 3.2.4 for Windows, then run it, and type: pkg load communications. There is no need to install communications package separately because it's installed by default. That's all.
Octave for Windows You can find here: Octave-Forge
Hi SanjayKKK
I think that is inversely, ie. a capacitor works as an accumulator (integrator) and an inductor works as a differentiator (providing that You think about a voltage as an output signal).
I would rather write:
y = [f(x + h) - f(x)]/h.
If You think about h as a unit increase previous...
