PURPOSE:To eliminate the useless initial acquisition time and to realize high- speed joining to a TDMA frame by identifying the station transmitting no burst through a reference station and allotting the initial acquisition time only to said station in case a large number of stations join to the TDMA frame. CONSTITUTION:A reception part 7 of an initial acquisition time allotment control system receives a reception burst and transfers the data to a reception data processing part 8. At the same time, a data burst non-transmission detecting part 6 detects a unique word of each station and decides a station where the detection is impossible for the words continuously in a fixed frequency or more. Thus no data burst is sent to said station, and the station number is given to a system control information generating part 5. The part 5 receives the burst assignment information and forms an overhead channel. This channel containing the initial acquisition time allotment information is applied to a reference burst generating part 4. Then the initial acquisition time is alotted only to the station that transmits no burst. Thus the station can join to a frame at a high speed. |
