Abstract :
An efficient combination of repetitive coded L-PPM with an ARQ protocol is presented which can estimate the channel state and adjust the link transmission rate. The protocol operation is modelled as a Markov chain and analysis results indicate the enhanced performance of the proposed scheme under adverse channel conditions
