Abstract (en)
[origin: US5647006A] A mobile radio terminal comprises a speech processor for processing a first and at least a further speech signal formed by noise and speech signal components and available as sample values. The sampled further speech signal is delayed by an adjustable delay value. Control means are provided which are used for forming gradient estimates. The control means are additionally used for recursively determining delay estimates from the gradient estimates. By rounding the delay estimates, the delay values are formed. Furthermore, their mutually time-shifted speech signals are added together by means of an adder device.
