Abstract:
Embodiments of the invention provide a method for discriminating between two types of encoding schemes for the frame control header (FCH) used in G3-type narrow band OFDM communications. The two modes for encoding are Differential with respect to the previous Symbol (DS) and Differential with respect to the Preamble (DP). This mode is sometimes referred to as “coherent” mode.
