A Study on Application of Reliability Based Automatic Repeat Request to Brain Computer Interfaces

Recently, a lot of research on a Brain Computer Interface (BCI) which enables patients like those with Amyotrophic Lateral Sclerosis to control some equipment or to communicate with other people has been reported. One of the problems in BCI research is a trade-off between the speed and the accuracy. In the field of data transmission, on the other hand, Reliability-Based Hybrid ARQ (RB-HARQ) has been developed to achieve both of the performances. In this paper, therefore, BCIs are considered as communications between users and computers, and Reliability-Based ARQ, similar to RB-HARQ, is applied to BCIs. Through simulations and experiments, it is shown that the proposed method is superior to other methods.
