Abstract

A method and apparatus for reducing the information error rate of a communication network. The apparatus comprises a selector device coupled to a Framer and to an Interleaver. The selector device is configured to receive system information and the Framer is configured to receive user information. The apparatus is coupled to equipment which operate the communication network based on system parameters. The apparatus and method of the present invention improve the coding and effectively increase the interleaving depth applied to user information thus reducing the information error rate of the communication network without having to alter or modify any of the system parameters.

Dependent claims

An apparatus for transmitting information in a communication network comprising:

a selector configured to receive system information, to forward an indication of a number of N identical copies to be generated and to forward an indication of an interleaving scheme, based on the system information;
a framer configured to receive the indication of the number of N copies from the selector, to arrange user information into information groupings and to generate N identical copies of each information grouping where N is an integer equal to 1 or greater and to forward the N copies;
and
an interleaver configured to receive the N generated copies of each information grouping from the framer and the interleaving scheme indication from the selector and to interleave the N generated groupings over a selectable number of time blocks of the communication network in accordance with said interleaving scheme to provide a reduction in a received information error rate.
