"Encoding method of voice, the system transmitter and receiver of the voice signal to encode and decode the input signal, decoder, mobile station and network element.Method and system for encoding and decoding the input signal.Where the input signal is divided into an upper and frequ00b3u00eancia band in a band frequ00b3u00eancia lower in processes of encoding and decoding.And where the decoding of the upper frequ00b3u00eancia band is performed using a signal along with the artificial parameters related to voice, obtained from the band of frequ00b3u00eancia below.In particular, the artificial signal is spread before being turned into a broad band signal containing a noise artificial colored band of frequ00b3u00eancia top and bottom.In addition, the voice activity information is used to define the periods of voice and non voice periods of the input signal.Based on the information of voice activity, different weighting factors are used to scale the artificial signal in periods of voice and in periods of non voice.
