Signal memory and dispersion complicate the issue of how best to observe and decide on digital bits. The Viterbi algorithm comes to the iterative rescue, with a way to perform the optimal ...

The Viterbi Algorithm, the elegant 41-year-old logical tool for rapidly eliminating dead end possibilities in reception of digital data, has a new application to go alongside its ubiquitous daily use ...

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers ...
