Performance Analysis of Queueing Systems with Systematic Packet-Level Coding

We study a queueing system operated with packet level coding. More specifically, we derive a closed-form approximation
for the queueing delay as well as an expression for the decoding delay of a system operated with systematic network
coding. Unlike previous works, the delay is considered on a per packet basis rather than per-block, thus taking into account the
low-latency property of systematic codes. Furthermore we study the trade-off between the coding gain and the decoding delay for
finite block lengths.
