Abstract

A communication system (100), comprising a first communication unit (112) communicating (118) with a second communication unit (122), said first communication unit (112) transmitting to said second communication unit a preamble (516) prior to a message, wherein the preamble is a concatenation of signals, said second communication unit receives and decodes the preamble (516) and compares the received concatenated signals with know pre-determined concatenated signals to determine whether an error has occurred in said preamble (516) or said first message.This enables a system employing the FAUSCH concept to carry more information than a simple request for a channel. For example, it could include the data rate of the required channel. It also allows an extra degree of flexibility when designing the protocols. It allows forward error correction to be applied to the channel. Hence, the receiver can detect and correct some transmission errors.
