Abstract

A data communication system comprises a transmitter for transmitting a fixed-length block of information, and a receiver for receiving the block. The fixed length block includes a plurality of sub-blocks, each having a variable length depending upon the data. When an amount of transmission data has a size less than that of the fixed-length data block the transmitter repeatedly arranges the information within the same fixed-length block in order to form the block. Thus the unused portion of the fixed-length block is effectively utilized to increase the reliability of the data communication. Additionally, error check codes may be stored within the data area to further increase reliability.
