Issue Date: | 1-Jan-1999 | Journal: | IEEE International Conference on Communications | Abstract: | © 1999 IEEE. The performance of maximum-likelihood decoding of trellis codes for moderate-To-high SNR is dictated by their distance spectrum. An improved version of a bidirectional algorithm is used to find cosets of convolutional codes for the EPR4 and EEPR4 channels with best (squared Euclidean) distance spectrum. Results are restricted to the class of totally trellis-matched codes. Distance spectra results for these new optimized codes as well as for some related previously published codes are tabulated. Moreover, we call attention to some codes that were erroneously tabulated in a previous paper. | URI: | https://open.uns.ac.rs/handle/123456789/15702 | ISBN: | 078035284X | ISSN: | 15503607 | DOI: | 10.1109/ICC.1999.765517 |
