Abstract
Frame synchronization between Asymmetric Digital Subscriber Line (ADSL) transceivers operating using Discrete Multi-tone (DMT) line code is effectuated by boundary detection logic executing a rapid, computationally simple correlation process. The invention is particularly suited for ADSL software modem implementations, where conservation of computing resources is especially critical, and loss of synchronization can lead to significant unrecoverable data errors.
