Abstract
A circuit arrangement in a data transmission system for selecting a diversity channel is described. The transmitted information and parity bits are applied in the receiver, over a channel switch and a code frame switch in serial fashion, to a parity bit register and an information bit register. Inputs to a first parity stage are connected to outputs of a number of cells of a first part of the parity bit register and to n1 cells of a first part of the information bit register. A code frame switch connects each channel to a second part of the parity bit register and a second part of the information bit register. A number of cells of the second part of the information bit register and the output of the first parity stage are connected to a further parity stage assigned to each diversity channel. The outputs of the further parity stages are connected to a quality evaluation stage which produces control signals with which the channel switch switches through one of the diversity channels.
