Abstract :
By analyzing the characteristics of the communication channel in the bi-directional digital wireless endoscopy system, this paper proposes an efficient control strategy of dynamically adaptive packet length for automatic repeat query (ARQ) scheme in this system. The mathematic formula of the strategy is given. The strategy assures not only the image communication quality but also the optimum communication power efficiency in the capsule. The implementation of the control strategy is also given out in this paper.
