Abstract :
The design of an efficient mobile data link protocol (MDLP) based on a Type II hybrid automatic request for repetition (ARQ) scheme using convolutional coding and code combining is presented. An adaptive coding scheme for the header is proposed and analyzed. Simulation results show significant improvement in throughput at low SNR as compared to conventional schemes. Precise specification of the MDLP using a formal description technique based on Estelle is outlined and discussed
