The only assumption lies on the perfect estimation of timing synchronization (one sample per symbol, optimum sampling time).
First, we focus on the estimation of timing drift.
This investigation presents a blind frequency estimation and timing synchronization algorithm.
Before frequency offset and channel estimation, a timing acquisition process is needed.
Carrier frequency offset estimation, symbol timing estimation, phase noise tracking, equalization, and detection are all implemented in fixed point in the FPGA.
However, because the number of samples used for CFO estimation and timing offset estimation is small, the normal method with low implementation complexity is low-power design.
The measuring of the frame period at receiver is used in the estimation of timing error in the tracking stage.
Considering single-carrier communication, the joint estimation of timing and carrier frequency offsets is studied in [359].
A joint estimation of timing, integer frequency offset (IFO), and PSS ID (sector ID) is carried out in module II.
The estimation of timing drift is first used to update the frame period and the starting position of next frame.
