What is meant by carrier recovery?
A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal's carrier wave and the receiver's local oscillator for the purpose of coherent demodulation.
What is meant by timing recovery?
The purpose of timing recovery is to recover a clock at the symbol rate or a multiple of the symbol rate from the modulated waveform. This clock is required to convert the continuous- time received signal into a discrete-time sequence of data symbols.
What is carrier recovery in digital modulation?
Carrier recovery refers to establishing a local carrier reference signal which accurately reproduces the frequency and, with some modulation methods, the phase of the carrier of the modulated signal.
How synchronization and carrier recovery is important in digital modulation?
Carrier synchronization is one of the key components in digital communication systems. Briefly, carrier synchronization concerns the estimation and compensation of the carrier frequency and phase differences between the transmitted signal and the corresponding received signal.
