Abstract
In order to synchronize wideband signals in time while reducing the necessary amount of processing, a number of narrowband signals (203, 205, 207, and 209) are modulated (503) on their own frequency sub-carriers, such that the summation of these modulated signals remains within the bandwidth of the wideband signal (201). This composite signal is transmitted (507) to a receiver, which uses a matched filter bank (405) to recover timing data from each transmitted frequency sub-carrier.
