In satellite communication uplink (transmission of signal from earth station to satellite ) & downlink (reception of signal from satellite to earth station) takes place TX & RX involves a finite amount of delay which is acceptable in data communication, but i audio & video TX this delay is unacceptable, overlapping/ alaising causes errors which demodulated by qpsk.
What else can I help you with?
Define downlink frequency?
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
What is the purpose of satellite communication?
The purpose of communications satellites are to provide telecommunication for companies around the world. In addition, communication satellites are also used for mobile applications such as communication to ships, vehicles, and planes.
Is a modem a widely used communication device?
Yes, whether you have Dial-Up, LAN, DSL, T1, Wireless or Satellite, you need a modem in order to convert the information to a format that your PC can understand. Therefore, it would be considered a "widely used communication device".
Which vacuum based device is widely used as a power amplifier in satellite communication system?
The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.
What type of antenna is used for satellite communication?
parabolic
What is agila2?

Where is plus 881international code?
The international dialing code +881 is designated for satellite phone services, rather than a specific country. It is used by satellite communication providers to facilitate calls from satellite phones to regular phones and vice versa. This code is part of the ITU's global mobile satellite service numbering plan.
