These are at least 1-year long projects. If you are an under-grad student and can commit for atleast one year full-time (can be six-nine months full time and remaining with course work) project work, then you can contact me. If interested then send me a email with subject “UG Researcher:(interests):(programming languages)”, for example “UG Researcher:(MobileApp, Signal Processing):(Matlab/Java/C++/C)” OR If you have an idea or interests then too you can contact me.
These are typically 1-2 years projects. If you graduated from one of the top colleges in India or abroad or are simply bored with your current job and/or would like to build up a CV for applying abroad for higher studies, then you are welcome to apply. This requires longer commitment for at least a year to two. Since this is a full-time, you will be compensated based on qualifications and experience. These will be advertised on this and institute job opportunity website.
In signal processing we have a concept of "short time analysis", isn't it just like life. We take a small window of events in time that happened in recent times and these get imprinted in our minds. After that time goes away, we move that window to another start time, and memories fade away from previous window. However during this short window, we see things as constant. In life when we see things as constant and have a concept of permanancy. The things appear to be permanent during the window of the time we see things. As an example a child going to school - in initial years they think they will continue to go to school forever, however that is not true. When we buy a house or a car we think it is ours forever, however its not. These things are there (or we may think they are ours or mine) till we can see them, hold them, drive them, stay in them. Thus the concept of permanent is there only till the window we can perceive them in our minds as ours, similarly in signal processing we consider, many atimes for ease of analysis and computation, and also for both speed and memory, that statistical characteristics of a windowed signal are constant or stationary. As in signal processing we cannot have a non-causal system, which is cause an effect, such is life when we do something then we see the cause and effect of it. Again as in signal processing we cannot determine future, such is life we think we can try to predict future by going to astrologer, however we can't. So based on the past and present we can guesstimate what can happen tomorrow, and so is in signal processing. In signal processing based on the past and current statistical properties of the symbols, we can make short term predictions.
