Which modulation is used in satellite communication

More Communication Systems Questions Q1. Consider the following statements: a. The speed of telecommunication satellite relative to earth is zero. Hence it appears to be stationary to a person on the earth. The frequency which is not transmitted in AM transmission is. In a communication satellite, the telephone channels are assembled in.

In television transmission, the type of modulation used for video is. In amplitude shift keying, transmission bandwidth is equal to. The process of super imposing information onto a carrier wave is called. A type of amplitude modulation in which carrier is suppressed is called. A fair coin is tossed N times. The probability that head does not turn up in any of the tosses is.

Testbook Edu Solutions Pvt. However, the OFDM signal has a higher PAPR than traditional modulation schemes, requiring a large back off to avoid the compression at a high output power level. Nonlinear effects generated by the high-power amplifier may introduce more distortions to a satellite system that causes a system failure. Therefore, characterizing the distortion performance of satellite RF components is essential for making a good system design.

Most communications systems optimize efficiencies in system designs, including spectral, power, and cost. The selection of modulation schemes for satellite communications depends on the communication channels, hardware limitations, and data throughput requirements.
