Luby Transform matlab code

Given a degree distribution (Ideal Soliton Distribution)

P(d) =1/K for d=1

=1/(d(d-1) ) for d=2,3,4……K.

For example when K=20, P(1)=1/20, P(2)=0.5 and so on

And the input x.

x=101100111010111001110100

Perform the following:

Step 1: Divide x into k symbols of equal size.

For example x1= 101100, x2=111010 x3=111001 and x4=110100. In this case k=4.

Step 2: Generate a degree d at random according to the degree distribution. Then randomly select d symbols from x1, x2….x4 and combine them using the XOR operation to generate the output symbol yn.

Continue the above until you have n symbols as the output where n=(1+a)k. where a is say 0.1.

SIr I am currently working with this.I want the matlab code for LT code.So,Please upload the matlab code for both encoding and decoding of Luby Transform

[Adarsh Reddy]

sir if you got the matlab code can you please share it! Even i'm doing the same
