Symbol synchronization, the ability of the receiver to synchronize to the first symbol of an incoming data stream [1], is a critical component in the design of an underwater acoustic modem.

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.
What is carrier and symbol synchronization?
Carrier and symbol synchronization are the key prerequisite for the accurate reception of the Quadrature Phase Shift Keying (QPSK) signal. The traditional synchronization methods have some intrinsic problems, such as slow speed, difficult to design the coefficients for the loop filter.
What are the types of synchronization in digital communication?
Digital communication systems using noncoherent modulation require two levels of synchronization 1-Frequency, 2-Symbol, 3-Frame synchronization.
What is carrier synchronization?
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.
