Recently, I’ve been ask to write a 30pages study comparing the different types of communication techniques applied to SOHO networks (residential networks). The subject was, in French, :
“Comparaison des différentes techniques de transmission de données, Solutions applicables à l’habitation particulière”.
Well, after some 6weeks of sleepless nite, and coffee doping, here it is, I hope this [...]

In the series of Digital Transmissions Studies, let’s study the following transmission Channel :
We will attempt to define the ideal matrix of the transversal equalizer in a few steps.

Well, it’s been some time we didn’t speak mathematics and electronics here, so let’s fix up things and do some applied communication filters. This post is mainly for my co-student who are working on the ELE203 examination (as me), which willbe held on this saturday (never too late to study huh ?)
Sorry guys, this blog [...]

Recently on a familly meeting, I’ve been asked to send my math book list to a cousin (hope him to go threw them for his own good).
Well, this is reminding me that I planned (long time ago) to open a book section containing the books I had the chance to get my hands on [...]
Since I am often sent expat in China this year, I have quite a few issues to follow all CNAM classes in France . . .
As a result, we are now approaching the second term examination period, (namely next week), and I’ll be in China as well. Fortunately, I succeeded to outsource my ENG110 exam [...]
Here is the problem:
Given 3 points , and verifying and , and . We want to know what cosinusoidal curve pass though those 3 points like :
Still guessing about it but, I couldn’t find an elegant way to find the minimal hamming distance of a code … till I finally got it !, here it is:
Basically the question falls to find the minimum amount of difference between two different codewords, say you got your codeword which is bit long, systematical [...]
Working on my next practical class (ELE109), I had the impression of something wrong in that text:
Let be the generator polynom of the code, the non systematical matrix can be defined by calculating , , and :
Well, that last one sound wrong … let’s check, it out, we can obtain the systematic [...]
Well, first semester is now finished (that was quite a hard job to manage 6 class at a time …), but I am glad to say I’ve done it (still waiting for some results though …).
Since CNAM does not really likes hollidays, the second semester started right after :’(, well, let’s go and see [...]
