A system and method utilize a dual correlation, one for the synchronization pattern (sync correlation) and one for the channel equalization pattern (CE correlation), to determine where the channel equalization pattern starts and thus establish frame synchronization. The system and method compare the two correlations and decides on the start of the channel equalization symbols when the CE correlation is larger than the sync correlation.

Dual correlation frame synchronization system and method

An ultra wideband receiver, based on multiband orthogonal frequency division multiplexing (MB-OFDM), combines digital data from multiple channels after signal processing and before decoding. The receiver provides a master controller that synthesizes packet synchronization, frame synchronization, and sampling frequency offset information from multiple channels into signals that simultaneously control all channels of the receiver.

The invention enables automatic gain control in ultra wideband applications over multiple channels and frequency bands.

A method is presented for packet detection and symbol boundary location using a two-step sign correlation procedure. When the correlation crosses a threshold, a packet detection signal is generated to initiate processing of downstream blocks, and a symbol boundary location signal is generated for use in aligning data during processing.
