Description

The GOLD-SX is part of a complete chip set which covers all functions of a mobile radio for the Global System for Mobile communications, GSM. A mobile terminal which contains this chip set can meet all performance requirements set down in the Technical Specifications for GSM, PCN and PCS-1900.

GOLD-SX is used for advanced features. The function of the GOLD-SX is dependent on its firmware.

The first version of the GOLD-SX performs Half-Rate speech encoding including Voice Activity Detection (VAD) and Discontinuous Transmission (DTX), as well as Half-Rate speech decoding including Discontinuous Reception (DRX,Comfort Noise).

The second version performs Enhanced Full-Rate speech coding including all the DTX functions as in Half-Rate speech
coding.
