Abstract
A system and method is herein described for the wide band acquisition of a high performance waveform in an environment with poor signal to noise ratio. The waveform acquired has a preamble with a plurality of frequency modulated Maximum Length Sequences and a period of pure carrier. In one embodiment, method provides an application specific integrated circuit (ASIC) for receiving the waveform, filter coefficients for use with the MLS's portion of the waveform, and filter coefficients for the pure carrier portion of the signal. Another embodiment may also include, for the MLS portion of the signal, detecting the signal through partial correlation, extracting waveform information, and estimating symbol timing. Yet another embodiment may further include, for the pure carrier portion of the signal, estimating the phase and frequency of the signal and providing those estimates to an ASIC.
