[0032] best practice
[0033] The present invention provides improvements to speech signal processing that can be implemented at a receiver. According to one aspect of the invention, the frequencies of the speech signal in the higher frequency region are synthesized using information in the lower frequency region of the received speech signal. The invention makes advantageous use of the fact that speech signals have harmonic content that can be extrapolated into higher frequency regions.
[0034] The present invention can be used in conventional wireline (ie fixed) telephone systems or in wireless (ie mobile) telephone systems. Since most existing wireless telephone systems are digital, the present invention can be easily implemented in a mobile communication terminal (eg, a mobile phone or other communication device). figure 1 A schematic depiction of functions performed by a communication terminal acting as a receiver according to various aspects of the present invention i...
