Abstract
A system and method enable wireless communication from one data processing system to a telephone network. The system and method establish a connection from a local transceiver to a base transceiver using echo cancellation techniques to remove various tones and noise. The system and method enable full duplex communication between the local transceiver and the base transceiver by using forward error correction algorithms to encode and decode messages therebetween, and by using an interleaving algorithm to protect against burst type errors.
