Because primary TDM/TDMA specific satellite channel intelligence of the present invention exchanges control subsystem up employing TDMA mode, so satellite burst MODEM must be used.Satellite burst MODEM preferably adopts TDMA working method at a slow speed.
When TDMA working method at a slow speed, user can create self-defining packet and sufficiently long preamble, thus utilizes standard satellite MODEM to receive this packet.The length requirement of preamble guarantees to make carrier lock, as shown in table 1.Satellite MODEM happens suddenly carrier wave by RTS control transmitting/closedown.This working method is adopted based on existence conditions satellite burst MODEM.
Frame structure of the present invention makes an explanation below.
A, frame structure design principle
Time division multiple access (TDMA) mode distinguishes different address with different time-gap, and each remote terminal only transmits in bursts in regulation time slot; In time, require these signals by regulation order successively by satellite repeater, non-overlapping copies, any moment is by the signal only having a station to send of satellite repeater.Therefore, need design tdma frame structure, the control signal avoiding different website to send is overlapping on satellite repeater; And improve satellite channel intelligence exchange control system utilance, reduce transponder free time.
Consider carrier acquisition time and transmission information amount, satellite channel intelligence exchange control system carrier information speed is chosen to be 64kbps, TDM carrier wave selects QPSK modulation, FEC3/4 error correction, and TDMA carrier wave selects BPSK modulation, FEC1/2 error correction, and carrier acquisition time is 60ms at least.Initial stage network size considers 8 far-end satellite earth stations.For reducing complexity, compressed information transmission cycle, time slot allocation selects fixing preassignment mode.Design adopts stratification frame structure, and be made up of frame, framing and time slot, its least unit is time slot.
B, protection time slot are determined
During TDMA carrier operation, must have unified time reference, each website time slot must be synchronous with time reference.Central station as time reference utilizes the TDM carrier wave of transmission continuously, periodically for each remote terminal provides time reference.Timing problem is a key issue of TDMA mode work, mainly comprises the process of two aspects:
A, when starting to launch, ensure that this burst accurately falls into the time slot of specifying, and other time slots can not be strayed into cause interference;
B, each point stand in the time slot work of specifying, maintain strict time relationship between them, and the phenomenon that can not overlap.Because the radio wave propagation air line distance of each remote terminal and central station distance satellite there are differences each other.Make central station send to the TDM carrier wave of satellite, each remote terminal receives and the TDMA carrier clock benchmark extracted exists deviation each other, and the information causing each remote terminal to be sent on satellite repeater may be overlapping.The simplest method adopts protection time slot to overcome its impact exactly.Guard time is greater than 2 times of the deviate of this maximum possible.
According to nationwide satellite time delay statistical conditions, then consider certain satellite drift, clock skew, guard time should be not less than 30ms.
C, frame structure are determined
Frame length is chosen and will be considered following principal element: frame efficiency and Time Delay of Systems; Business datum segment length is the integral multiple of 8bit; The station number of the scale of network and the interior work of network, frame longer frame efficiency is higher, and open ended station number is more; Capturing carrier and Clock Extraction time.Design and divide frame period identical to TDMA carrier wave to the TDM carrier frame cycle with entering.
Capturing carrier lock in time: Ts=512 × 8/64=64 (ms) >60ms;
Guard time: Tp=252 × 8/64=31.5 (ms) >30ms;
Single remote terminal tdma frame cycle: T=(512+4+1200+252) × 8/64=246ms;
