Satellite Communication Frequency Modulation

Ssb is using in satellite communication where voice signals are multiplex to make a baseband composite signal. Fm is no longer used for tv services and even in data services fm is not really used. 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.

Satellite communication frequency modulation.

Other equipment that are essential for creating a satellite link include satellite antennas and frequency converters. In these applications its particular advantages can be used to good effect. Data to be transmitted are transferred to a modem from data terminal equipment e g. The most common application of the ssb in the satellite communication is to multiplex voice signals into a composite baseband signal.

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. 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. A computer the modem usually has intermediate frequency if output that is 50 200 mhz however. 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.

Frequency modulation is widely used in many areas of radio technology including broadcasting and areas of two way radio communication. Focuses on modulation techniques for modern satellite communications from generating and analyzing the signals to the impacts of phase noise on modulation quality. The angle modulation is further divided into frequency and phase modulation. 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. 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. In mobile satellite communication the most commonly used digital modulation system have been bpsk and different forms of qpsk.
