Abstract:
1. A method for decoding channel-encoded date comprising: (a) receiving encoded symbols; (b) compressing the encoded symbols to obtain compressed symbols; (c) decoding the compressed symbols using a first look-up table that stores information approximating output of an algorithmic decoding process to obtain decoded symbols; (d) arithmetically combining the compressed symbols with the decoded symbols to obtain a first result; (e) decompressing the first result to obtain a decompressed first result (f) interleaving the decompressed first result to obtain an interleaved first result; (g) compressing the interleaved first result to obtain a compressed, interleaved first result; (h) decoding the compressed, interleaved first result using a second look-up table that stores information approximating output of an algorithmic decoding process to obtain a decoded first result (i) arithmetically combining the decoded first result with the compressed, interleaved first result to obtain a second result; (j) decompressing the second result to obtain a decompressed second result; and (k) de-interleaving the decompressed second result.
