Well It seems quite a time, I had updated my last post on this Blog.
But now with solid grounds, I had started my M.Sc thesis in Cetecom telecommunication Lab in Germany.
I will write and share my whole experience throughout my Journey to solve the Problem of Non-linearity. How much it would improve empower Society by conducting research.
Few observations From transitioning from Lecture based to Independent based Learning:
1) Materials need to be explored on self-study basis.
2) Reasoning skills play a major role to understand the problem and to look for the solution on the right direction.
3)Consumes time though it will be an enjoyable run.
4)Focusing on the smaller details will create a situation to handle the problem very efficiently.
On side with Academic Lectures:
A)Material will be consolidated so less time to consume.
B) Need to think how Prof might have solved the problem.
C) “Exam prospective result is just credits but in thesis the goal makes us to push the Human race forward”…
I’ve always wonder ‘Ain’t that cool to take a break for Summer school’. Apparently, last week I got a opportunity to visit TU-Dresden(Technische Universitat), Germany. Microelectronics was always a fascinating thing which no one could less estimate because ‘Every chip counts for the computation we do with our computer’. The every nm(nanometre) of it’s size measures the capability of computation. As, We know breaking Moore’s law will be the next big thing in the silicon sector I just wanted ‘How industry experts try to solve Manufacturing and Moore’s law problem’.
Aside:though the event was held last week I din’t find time, So my write-up won’t be chronological & it is non-linear narrative !
Tada…. Now I am here in TU-Dresden!!
Day-1 (Inaugural and Meet up)
Impressions from the first Inaugural speech by Prof. Johann Bartha(TU-Dresden)
the cloud nine moment was when professor introduced different people form various University … Gladly I was the Only one from Saarland University.
Day went well with loads of talk and finally the awe moment ,, Yep, the Music & sight seeing of City-Dresden.
Few clicks ….
The best advice I’ve ever heard to a question like this was something like “No problem, don’t motivate yourself, stay a loser” (in Russian, not sure how good the translation is).
Asking advise from other people doesn’t work.
Browsing Internet and Quora doesn’t work. You just sit down and study for 12 hours per day. Or you don’t.
This might sound harsh, but that’s pretty much what I started to do when I was in 8th grade, what I kept doing for the next ten years and more-or-less what I keep doing nowadays. And you know, I love it when people say “It’s easy for you, you’re so smart”. It isn’t easy, nowhere near that, but it’s worth the effort.
Leaving other Stereotypes. Germans have the great culture of Discipline being‘PUNCTUAL’ it’s a timely gift possessed by the entire nation .
Few occasions to cite:
1. Business meetings- They would like to start the meetings on time irrespective of people. They don’t start early nor late but They start ‘On-time’.
2. It holds true for Family gathering apart , the Transit in Germany will be consistent and on time
[Image :Train to arrive the Bahnhof(station) on-time]
The Local ‘DB’(Deutsche Bahn) arrives on time . Despite it’s timing native Germans say they are inconsistent but compared to US standards they are quiet consistent.
Though,there exists many characters to define a German quality but personally ‘Punctuality’ defines there discipline , nature of work. work life balance etc..,
‘Time management’- Would be the take home lesson for everyone from Deutschland!
Walsh codes (a.k.a Walsh-Hadamard codes) are a set of perfectly orthogonal codes used to separate users on the downlink (DL) channel in CDMA systems (for example in CDMA2000, UMTS cellular standards etc.). Code orthogonality between two codes W_i and W_j is defined as
These codes can be generated iteratively. Here is a simple illustration of a binary Walsh code tree.
As you might notice, any two codes in the same level or codes in different branches (at different levels) are perfectly orthogonal (called OVSF codes – Orthogonal Variable Spreading Factor Codes). The different levels of the tree correspond to different spreading factors (SF) for the code (which translates to different data rates – higher SF->higher data rates).
The code tree itself is easy to construct when you observe the pattern. If the code at a given level n is x (with SF 2^(n-1)), the codes generated at the next level n+1 are [x x] and [x -x] (with SF 2^n). You may also want to look into the construction of theWalsh matrix.
An important requirement to keep in mind for the orthogonality condition to work is that the codes must be synchronized in time and this is easier to achieve on the DL where a single base station is orthogonalizing multiple users in its cell area.
Aside: Walsh codes are also used for M-ary orthogonal modulation on the uplink (UL) channel for each user.
Ever wonder what the latest technologies on Mobile communications like CDMA, GSM, 3G, 4G, etc. mean?
They are different types of cellphone technology.
They are different technologies:
