| Abstract(in English) | We apply (n, k, m) convolutional codes in which elements in generator matrices are the ones over a finite field toHybrid ARQ combining with retransmission mechanisms, and evaluate the number of transmitted packets and the number oftransmissions. We assume star topology and independent model for a transmission model, and compare two retransmissionmechanisms: (1) one which has been applied with Reed-Solomon code, and (2) one which choose transmitted packetsconsidering the constraint length m. We use computer simulation for (14, 7, m) and (6, 3, m) convolutional codes to observe theeffects of four parameters, that is the number of receivers, constraint length m, packet loss probability, and redundancy at initialtransmission PF, to the number of transmissions and transmitted packets. Simulation results showed that a PF which minimize number of transmitted packets exists for given packet loss probability, number of receivers, and constraint length. Also, the number of transmitted packets can be reduced by the retransmission mechanism which consider m. |
