A system, apparatus, and related method for receiving and correlating Manchester encoded data signals includes a receiver for receiving 1090ES/ADS-B or other Manchester encoded signals. A sampler extracts and oversamples data strings from the received signals. Sample correlators compare the oversampled data strings to oversampled versions of each possible pattern for the extracted data string and determine a score indicating how closely the possible pattern (or its oversampled counterpart) matches the extracted data string (or its oversampled version) on a bitwise or symbolwise basis. The system outputs correlated and decoded data string most closely matching the extracted data string based on the set of determined scores.
