Performance Analysis of Double Channel SW-ARQ System
Suoping Li, Zhongyu Bai, Mei Liu · Advances in computer science research · 2015
An double SW-ARQ system model has been established for wireless communication in this paper.We analyzed the packet average delay for the system by an alternative method of retransmission, and recognize the packet's number in the buffer at receiver as the initial state of the system, the final state of the buffer reaches the channel's number by a limited times of retransmissions.For this complete transmission process, the packet average delay formula is obtained based on Markov state transition probability matrix, and make a comparative study how to control the optimal packet length to guarantee the largest throughput.
