The most fundamental digital modulation techniques are based on keying: PSK (phase-shift keying): a finite number of phases are used. FSK (frequency-shift keying): a finite number of frequencies are used. ASK (amplitude-shift keying): a finite number of amplitudes are used.
Read moreWhy are digital modulation techniques used in satellite communication?
The advantages provided by digital modulation techniques include: Better performance . Better Error detection and correction efficiency. Better Signal to noise ratio so less prone to interference or noise.
Read moreWhat are modulation techniques?
Modulation is the process of converting data into electrical signals optimized for transmission. Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method .
Read moreWhat is a satellite modulator?
A satellite modem or satmodem is a modem used to establish data transfers using a communications satellite as a relay . A satellite modem’s main function is to transform an input bitstream to a radio signal and vice versa.
Read moreWhy we use digital modulation techniques?
Digital Modulation provides more information capacity, high data security, quicker system availability with great quality communication . Hence, digital modulation techniques have a greater demand, for their capacity to convey larger amounts of data than analog modulation techniques.
Read moreWhat are the different digital modulation techniques used in mobile communication?
Digital Modulation can further be classified into four types:
Read moreWhat is digital modulation and its types?
There are three types of digital modulation, and they are: Amplitude shift key (ASK) Frequency shift key (FSK) Phase shift key (PSK)
