TERMINAL CONTROL DEVICE FOR REFERENCE STATION IN TDMA SATELLITE COMMUNICATION SYSTEM |
摘要 |
A terminal control device for a reference station in a TDMA satellite communication system includes means for generating a parallel acquisition window applicable to a parallel initial acquisition system and a sequential acquisition window applicable to a sequential initial acquisition system each in a TDMA frame, and selector means for selecting either one of the two different kinds of windows. The device selectively uses the two different acquisition systems and, thereby, accomplishes the advantages of both of the systems at the same time, i.e. short terminal buildup time and high TDMA frame utilization efficiency. |
