Satellite Communication Frequency Modulation
The angle modulation is further divided into frequency and phase modulation.
Satellite communication frequency modulation. 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. Other equipment that are essential for creating a satellite link include satellite antennas and frequency converters. The most common application of the ssb in the satellite communication is to multiplex voice signals into a composite baseband signal.
Data to be transmitted are transferred to a modem from data terminal equipment e g. A computer the modem usually has intermediate frequency if output that is 50 200 mhz however. Focuses on modulation techniques for modern satellite communications from generating and analyzing the signals to the impacts of phase noise on modulation quality. 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.
In mobile satellite communication the most commonly used digital modulation system have been bpsk and different forms of qpsk. Enable browser cookies for improved site capabilities and performance. Frequency modulation is widely used in many areas of radio technology including broadcasting and areas of two way radio communication. Ssb is using in satellite communication where voice signals are multiplex to make a baseband composite signal.
A satellite modem is not the only device needed to establish a communication channel. 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. Fm is no longer used for tv services and even in data services fm is not really used.
