What is symbol 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 symbol timing synchronization?
Symbol timing synchronization has a unique purpose: to find the optimal instants when downsampling a sequence of samples into a series of symbols. In other words, it focuses on selecting the “best” sample out of every group of samples, such that this selected sample can better represent the transmitted symbol.
