TWC system has high requirement for the real-time of frame transmission. In order to improve the frame delay performance on TWC system,aiming at the signal part predictability of the external antennas in TWC,propose a new scheduling algorithm: the earliest leave algorithm. On TWC system,RSSI between the external antenna is a unidirectional translational relationship,with this relationship,the earliest leave algorithm can predict the leave time on each external antenna at the frame arrival time,then choose t...
