Abstract
A wireless device decodes Direct Sequence Spread Spectrum (DSSS) encoded data and identifies data that can not be successfully DSSS decoded (invalid data). A checksum operation uses successfully decoded DSSS data (valid data) to correct the identified invalid corrupted data. The improved error correction leverages the valid and invalid bit information normally provided in DSSS systems to more effectively correct corrupted data bits. The improved error correction increases the processing gain of wireless devices thus increasing the effective wireless range without having to increase transmit power.
