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.
