Regarding Optimality of Huffman Code
Dear Participants,
There is one common doubt which is being asked by
many of you individually and I would like to address it to all. The
question is regarding the optimality of Huffman code. Many of you are
asking, for which category/class of codes Huffman Code provides minimum
average length ?
Is it optimal for some particular class of the codes or is it optimal among all source codes ?
Let me discuss in detail.
First, note following points:
1. Uniquely Decodable Codes is a subset of all possible codes.
2. Instantaneous Codes and Prefix Free codes are same and can be used interchangeably.
3.
Instantaneous/prefix codes form a subset of Uniquely Decodable codes
which means there exist some codes which are Uniquely Decodable but not
Instantaneous.
4. Macmillan's Inequality assures that any set of
codeword lengths achievable in Uniquely Decodable Codes is also
achievable in Instantaneous Codes which means that we can restrict our
search to only Instantaneous codes.
5. Huffman code generates
Instantaneous Codes and is optimum for a given model, i.e, set of
probabilities. Using point-4, we can say Huffman Code is also optimum
among the class of Uniquely Decodable Codes.
You can develop a
Vein Diagram (used in set theory) to understand the containment of above
set of codes using the points mentioned.
In the last, I just want
to emphasize the fact that when we say "among all source codes" it means
the class of Uniquely Decodable Codes because if a source code is not
uniquely decodable then it is useless.
Please let me know if some point is not clear.

MATLAB Assignment-1
Dear Students,
Some students have been requesting practical MATLAB assignments for the course. Hence we have decided to include some problems related to MATLAB level system implementation. The first MATLAB assignment is attached. Once you solve the assignment you can send a PDF with your detailed answer + plots + code to the TAs for evaluation. Please also note that the MATLAB assignments are OPTIONAL and purely to enhance your understanding. These will NOT be counted towards the final exam score.
