  • Echo suppression for compressed speech with only partial transcoding of the uplink user data stream
    Publication number: 20060160581
    Abstract: Disclosed is a method for suppressing (10) echo (z(t)) in uplink data (y(t), 12-16) originating from a terminal (2, 3), said method allowing a delay and a decrease in quality during echo suppression of uplink data originating from a wireless terminal (2, 3).
