This report addresses modulation and synchronization techniques for a multi-frequency time-division multiple-access (MF-TDMA) system with onboard processing. The application of the 1VIF-TDMA system is for VSAT-type terminals with mesh connectivity and destination-directed packet switching onboard the satellite. In such a.
Time Division Multiple Access or TDMA is a method used to enable multiple earth stations or VSAT terminals to transmit intermittently on the same frequency, but with the timing of their transmissions so arranged that the bursts do not overlay when they arrive at the satellite 5/5(2).

These conditional probabilities are plotted in Figure , but are scaled by the a priori probabilities P 1 the show how the possible voltages v are assigned to the two regions V 1 and V 2 in accord with (). in Figure a the a priori probabilities are equal for the two possible messages, and the decision threshold A/2 given by () falls halfway between zero and A. Currently wideband CDMA (W-CDMA) and OFDM/TDMA techniques are successfully in use in terrestrial mobile multimedia systems. Therefore, these two Multiple Access schemes (MASs) are getting considerable attention  in mobile multimedia communications for Non-Geo Stationary Satellite .

Publication date TZ Publisher. Restrictions imposed in the problem correspond to specifications for recent TDMA systems, and include: communication based on four-phase shift keying with differential encoding and coherent demodulation, or 4-phase DCPSK; burst identification based on an identification code following the UW; an aperture gate used in the retention mode to reject Cited by: 1.
Network Synchronization in a TDMA system. Network synchronization is required to ensure that all bursts arrive at the satellite in their correct time slots. For this purpose, timing markers are provided by the reference bursts, which are tied to a highly stable clock at the reference station and transmitted through the satellite link to the traffic stations.
The paper presents frame and burst acquisition in a satellite communication network based on time division multiple access (TDMA) in which the transmissions may be carried on different transponders. A unique word sequence can serve both purposes.

Time-division multiple access is a multiple access scheme, which is widely used in VSAT and broadband satellite systems and the GSM cellular mobile systems. In time-division multiple access (TDMA), the available channel bandwidth in its entirety is used by every user, but the users take turns in making use of the channel in a timely manner.
In other words, the channel is sequentially time-shared. Frame and Burst Acquisition in TDMA Satellite Communication Networks with Transponder Hopping. Compact and high performance TDMA terminal for satellite communication Abstract: A TDMA (time-division multiaccess) terminal for satellite communication systems is proposed.
A transponder hopping function has been realized using only a single modem and synchronization unit for each reference and traffic TDMA device, reducing cost by: 5.

Satellite Communication 1 In general terms, a satellite is a smaller object that revolves around a larger object in space. For example, moon is a natural satellite of earth.
We know that Communication refers to the exchange (sharing) of information between two or more entities, through any medium or channel. Satellite In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavor.
Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon In satellite communication, signal transferring between the sender and receiver is done with the help of satellite.
Conclusion: In order to understand advantages of satellite communication and disadvantages of satellite communication, one has to understand satellite communication basics.
