Abstract

A digital data communication system comprises a plurality of transmitting stations (TS1...TSN) and at least one receiving station (RS) connected by a multi-access non-destructive channel. In the figure the channels are provided by frequency division multiplexing over optical fibres which are coupled by a star coupler (SC) although other methods of channel separation may be applied. The transmitting stations each comprise a data source (DS1) which provides data to a coder (C1) and the coded signals provided by the coder are transmitted by a transmitter (Tx1). The coder is arranged to provide sufficient redundancy to allow the receiving station to receive substantially all of the data signals from all of the transmitting stations to be received regardless of their respective times of transmission. In this way a 'send it and forget it' communication system may be provided which does not require channel allocation, system-level acknowledgement or expensive receiving stations. Transmission efficiency is maximised for a given throughput and reliability if the coders are arranged to provide Maximum Distance Separable Coding (MDS).
