Abstract
A method of generating a puncturing pattern for use with a 1/n convolutional code having a predetermined code rate is disclosed. The 1/n convolutional code uses a predetermined set of binary generator polynomials comprising a first generator polynomial and a second generator polynomial, wherein the second generator polynomial has more non-zero coefficients than the first generator polynomial. For each of a plurality of candidate puncturing patterns, transmission of data over a noisy channel is simulated, the data being encoded using the 1/n convolutional code punctured in accordance with the respective puncturing pattern. A transmission error rate is determined for each candidate, and the error rates are compared to identify a candidate that has a lowest error rate. The plurality of candidate puncturing patterns includes only patterns that puncture no more coded bits generated by the second generator polynomial than they puncture coded bits generated by the first generator polynomial.
