Abstract
A digital communication apparatus interleaves multiple bit sequences of a predetermined length from a plurality of input signals all at one rate to a single output data stream at a higher rate. Normally the multiple bit sequences will be bytes. The apparatus comprises for each input signal (IN1-In4) a first array (10-13) of storage circuits for storing sequentially in series each multiple bit sequence of predetermined length, the first arrays (10-13) being arranged in parallel, a reader for reading in parallel each of the stored bit sequences in the first arrays into second arrays (90-93) of storage circuits so that the bits of the stored sequences are interleaved, and a combiner (20) for combining the sequences output from the second arrays in such a manner that the output data stream contains the original multiple bit sequences interleaved so that in the final output stream a multiple bit sequence from one input signal is separated from the next multiple bit sequence of that signal by multiple bit sequences from each of the other input signals.
