WebSymbol timing recovery is an important function of any digital receiver. In the wireless mobile data field the task of establishing accurate symbol timing at the receiver is complicated by the time varying channel. This time varying channel also makes the use of coherent modulation schemes significantly more difficult. WebSep 9, 2024 · $\begingroup$ Would you consider using an actual timing loop? I think you will find it actually simpler in implementation and more robust that a “brute-force” approach. The preamble sequence is good to establish initial acquisition for the packet especially in lower SNR conditions and then the timing loop will use current symbols along with past …
