Rafi Rabipour, Dominic Ho: Echo canceller for VOIP networks. TELEFONAKTIEBOLAGET L M ERICSSON, Coats & Bennett PLLC, February 23, 2016: US09270830 (1 worldwide citation)

An echo canceller in an IP network includes an adaptive filter that models the echo path between a receiving output port of the echo canceller and a sending input port. The adaptive filter filters a receiving input signal to generate an estimate of an echo signal. The estimate of the echo signal is ...

Rafi Rabipour, Dominic Ho: Echo canceller for VOIP networks. TELEFONAKTIEBOLAGET LM ERICSSON, Coats & Bennett PLLC, August 16, 2016: US09420114

An echo canceller for an IP network includes an adaptive filter that models the echo path and generates an estimate of the echo signal from a receiving input signal. The echo canceller subtracts the estimate of the echo signal from a sending input signal to generate a sending output signal with redu ...
