Focuses on modulation techniques for modern satellite communications from generating and analyzing the signals to the impacts of phase noise on modulation quality.
Satellite communication frequency modulation.
If the frequency of the carrier wave is varied in accordance with the instantaneous value of the modulating signal then such a technique is called as frequency modulation.
Another form of ssb is using in the mobile satellite communication is known as the acssb amplitude companded ssb because in mobile satellite service efficiency of the bandwidth is desired.
The most common application of the ssb in the satellite communication is to multiplex voice signals into a composite baseband signal.
A satellite is a body that moves around another body in a mathematically predictable path called an orbit a communication satellite is nothing but a microwave repeater station in space that is helpful in telecommunications radio and television along with internet applications.
In these applications its particular advantages can be used to good effect.
Another form of ssb is using in the mobile satellite communication is known as the acssb amplitude companded ssb because in mobile satellite service efficiency of the bandwidth is desired.
Ssb is using in satellite communication where voice signals are multiplex to make a baseband composite signal.
The angle modulation is further divided into frequency and phase modulation.
Fm is no longer used for tv services and even in data services fm is not really used.
Other equipment that are essential for creating a satellite link include satellite antennas and frequency converters.
It is not surprising that higher order modulation are providing the better performance and efficient as well but they are more sensitive to the channel impairments.
In mobile satellite communication the most commonly used digital modulation system have been bpsk and different forms of qpsk.
A satellite modem is not the only device needed to establish a communication channel.
Fm used to be used for analogue tv via satellites because it had excellent noise immunity compared to am and provided a relatively good signal lock.
