Method and apparatus for signal degradation measurement |
摘要 |
A method of measuring the degradation of a data stream owing to the influence of errors thereon is disclosed. Unlike known degradation measures, a measure calculated in accordance with the present invention takes into account the variation in the significance of an error in dependence upon the elements which are affected by it. A particular application of the method to the selection of one of a number of possible speech coding methods for use in transmitting speech across a radio link (20) from a mobile phone (10) to a base station (30) is described.
