All of the error correcting block codes used in P25 are the sort where the codeword includes the encoded data verbatim; the code appends bits used for error correction, but a receiver can ignore those and just pull out the data bits. This greatly increases the likelihood of post-decoding bit errors, but it works fine when the SNR is good. -------------- next part -------------- An HTML attachment was scrubbed...
