Abstract

The focus of this paper is on ways to improve the quality of Group III facsimile on intermediate data rate (IDR) satellite links. It is concluded that, unless the performance objectives of satellite systems significantly exceeds those derived from CCITT/ITU-T Recommendation G.826, fiber optic cables will become the preferred choice for international transmission. The following approaches to facsimile quality improvement are examined: increasing the reliability of the IDR link either by augmenting the transmission power or by using a more robust error correction coding or both; and enhancing the operation of the circuit multiplication equipment (CME) for facsimile by introducing a service-specific forward error correction (FEC) coding for facsimile.<>
