FBMC Training Symbol Delay-Overlap Synchronization

The patent merges the training symbol with data symbols by using delay-overlapping transmission, where the training symbol is transmitted with a time delay and overlapped with subsequent data symbols. This combining approach allows synchronization functionality to be integrated within data transmission time resources, eliminating the need for separate synchronization time slots while maintaining synchronization performance.

The transmitted signal serves multiple functions simultaneously: it carries both training information for synchronization and data information for communication. The delay-overlapped training symbol embedded within data symbols enables the system to perform synchronization and data transmission using the same time resources, achieving multi-functionality in resource utilization.

Instead of using static repeating patterns, the patent employs dynamic delay-overlapping where the training symbol is transmitted with a specific time delay and overlapped with data symbols. This dynamic approach creates effective repeating patterns through the overlap structure itself, achieving synchronization accuracy without requiring complex pattern generation mechanisms.

The delay mechanism acts as an intermediary that transforms the training symbol into an effective repeating pattern when overlapped with data symbols. Rather than directly generating complex repeating patterns, the system uses the delay and overlap operation as a mediator to create the necessary pattern structure for accurate synchronization.

The patent combines multiple training symbol transmissions into a single delay-overlapped structure where one training symbol is transmitted with delay and overlapped with data symbols, effectively creating multiple useful signal components from a single transmission event. This merging approach provides robustness equivalent to multiple training symbols while using fewer frequency resources.

The delay-overlapping creates continuous useful signal components throughout the transmission period. The training symbol, when delayed and overlapped, provides continuous correlation opportunities for synchronization across the data symbol duration, maintaining robustness without requiring discrete multiple training symbol transmissions that would consume additional frequency resources.
