Title: Echo eliminating method
Inventor: KANEMASA AKIRA
IPC: H04B3/23
Filed: 1984-09-21
Abstract: PURPOSE:To simplify the control, to decrease a circuit scale and to reduce a converging time by providing a circuit comprised of a subtractor and a delay element, a circuit comprised of an interpolation filter, a polarity detector, a coorelation device and a multiplier, and a switch is place of a conventional random signal generator. CONSTITUTION:A delay circuit 17 gives the delay of Tsec (1 bit width) and a value subtracting a value before Tsec from the present value appears at the output of a subtractor 16. The condition that a probability obtaining accurately the polarity of a residual echo component in a signal difference being the output of a subtractor 10 is not zero is established by a polarity detector 12 through the addition of both circuits so as to guarantee the adaptivity of an adaptive filter 8. The correlation of outputs of the polarity detectors 12, 19 is calculated by a correlation device 20 and multiplied by 2alpha (alpha is a constant) with a multiplier 21,and the result is fed to a multiplier 13. A polarity having a value subtracting the value before Tsec from the present value appears at the output of the detector 12 as to the said difference and the polarity of echo replica appears at the output of the detector 19. Then the output of the correlation device 20 is large or small depending on the quantity of a residual echo. Thus, 2alpha times of scaling is applied to the output of the correlation device 20, the result is used as a step size, the polarity of the output of the detector 12 is given thereto and fed back to an adaptive digital filter 8 so as to reduce the converging time.
