Optimize the degree distribution of a digital fountain code for a file of K = 10 000 packets. Pick a sensible objective function for your optimization, such as minimizing the mean of N, the number of packets required for ...
Question: A wave pulse travels along a string at a speed of 200 cm/s. What will the speed be if: 1. The string's tension is doubled. 2. The string's mass is quadrupled (but its length is unchanged). 3. The string's lengt ...
Derive the ideal soliton distribution. At the first iteration (t = 0) let the number of packets of degree d be h 0 (d); show that (for d > 1) the expected number of packets of degree d that have their degree reduced to d ...
