ABSTRACT:
A data packet is transmitted by dividing it into sub-packets, for example by distributing successive bytes of the data packet to different sub-packets each containing at most p.sup.n -1 symbols, where p is a prime number, and transmitting the sub-packets along two or more respective paths. CRC checksums are added to the sub-packets, the checksum for each path being generated using a different and respective generator polynomial of degree b. These generator polynomials are selected so that, for arithmetic carried out modulo p, each polynomial has a respective factor of degree at least b-n+1, and the collection of polynomials which are each exactly divisible by all such factors constitutes a BCH code. As a result the system has advantageous properties in respect of error detection and implementation.
