Abstract

Broadcast channel delay Delays Encoding erasure channel network coding Probabilistic logic random linear combination Receivers Stochastic processes Transmitters Upper bound
We consider a transmitter broadcasting random linear combinations (over a field of size d) formed from a block of c packets to a collection of n receivers, where the channels between the transmitter and each receiver are independent erasure channels with reception probabilities q = (q 1 ,..., q n ). We establish several properties of the random delay until all n receivers have recovered all c packets, denoted Y n:n (c) . First, we provide lower and upper bounds, exact expressions, and a recurrence for the moments of Y n:n (c) . Second, we study the delay per packet Y n:n (c) /c as a function of c, including the asymptotic delay (as c → ∞) and monotonicity (in c) properties of the delay per packet. Third, we employ extreme value theory to investigate Y n:n (c) as a function of n (as n → ∞). Several results are new, some results are extensions of existing results, and some results are the proofs of known results using new (probabilistic) proof techniques.
