Abstract
Embodiments of a spread-carrier self-detecting code (SCSDC) receiver with summed-delay processing (SDP) and method are generally described herein. In some embodiments, the SCSDC-SDP receiver is arranged to generate a chip-matched filter output from a received spread-spectrum signal and perform SDP on the chip-matched filter output with a plurality of delay-processing chains. The SDP may include multiplying a conjugated and delayed chip-matched filter output with the chip-matched filter output and applying a code-matched filter that is matched to a delay-multiplied code. The outputs from the code-matched filters of each delay-processing chain may be coherently combined to provide an output having correlation peaks for use generating frequency error and timing information.
