Abstract

Apparatus and methods for transmitting and receiving a digital data signal. At the transmitter side, packets of p m-bit digital words in a digital signal are error protection encoded to produce error protection encoded packets of n m-bit digital words making up an error protection signal, where n>p. The error protection encoded packets are converted into converted packets of digital words to form a channel encoded signal, which signal is supplied to a transmission medium. The conversion involves use of a generator for supplying a fixed auxiliary packet of n digital words; a calculation unit for calculating in a Galois field GF(2m) a converted digital word in accordance with the formula DWi+ alpha .FWi, where DWi and FWi are the binary values corresponding to the i-th digital words in the packet to be converted and the auxiliary packet, respectively, alpha is a binary value, and the converted digital word is the i-th converted digital word in the converted packet, where i runs from 1 to n; and a digital sum value determining unit for determining the digital sum value of at least a converted packet in the channel encoded signal. The calculation unit determines a value alpha def with the converted digital words obtained by the Galois field GF(2m) calculation of DWi+ alpha def. FWi so as to obtain the converted packet, the value alpha def for alpha being such that a running digital sum value of the converted packets shows a desired pattern as a function of time. The receiver side operates in an opposite manner.
