Summary:A method and receiver are disclosed for the blind detection and synchronization of data packets are disclosed. According to one aspect, a method includes generating a running histogram of received sample values for each of a plurality of frequency bins and symbol timing phases, the running histogram spanning a most recent block of symbols representing a candidate synchronization (sync) word. The method also includes, for each symbol interval: analyzing the histogram to estimate symbol timing phase, DC offset and frequency offset. The method also includes determining a first candidate sync word based at least in part on the symbol timing phase, frequency offset and corresponding DC offset the first candidate sync word representing a most recent vector of bits associated with the first candidate sync word. The method further includes discerning a lower address part (LAP) obtained from the first candidate sync word to enable detection of a packet.
