Performance evaluation of Go-Back-i-symbol ARQ scheme applicable to meteor burst communications

In this paper, we propose a new ARQ scheme, named Go-Back-i-symbol (GBi) ARQ scheme which is suitable to Meteor Burst Communications (MBC). The scheme is based on the Viterbi decoding algorithm for convolutional codes and can achieve symbol-wise retransmission, so that it has high throughput performance for packet communication systems over time varying short burst channels such as MBC channels. We also propose a practical transmission protocol for applying the GBi-ARQ scheme to MBC systems. Comparing to a conventional block-wise ARQ scheme, the effectiveness of the proposed scheme is shown by computer simulations.
