Abstract
A frame delimiter detection system and method includes a phase differentiator and buffering module, a phase-to-I/Q reformatting module, a dot product module, an I/Q-to-polar reformatting module, a dot product comparison module, and a frame delimiter detection module. The method may include receiving in-phase and quadrature-phase (I/Q) formatted frequency domain input samples configured as a frame delimiter in a communication packet. An I/Q formatted dot product may be generated from the I/Q formatted frequency domain input samples and a reference pattern indicative of an expected frame delimiter. Further, a frame delimiter detection signal may be generated based on a magnitude of the I/Q formatted dot product.
