Title: Method of eliminating inter-code interference by decision feedback
Inventor: KANEMASA AKIRA
IPC: H04L25/03
Filed: 1985-09-02
Abstract: PURPOSE:To reduce the scale of the hardware by detecting a pattern when the sum or subtraction of a present difference signal and a signal before a prescribed second is coincident with an inter-code interference component so as to control an adaptive filter for the update of coefficient. CONSTITUTION:After a difference signal is obtained in the adaptive filter 5 by subtracting the pseudo inter-code interference from a reception signal including the inter-code interference, the difference signal and a delay signal are added to obtain a residual inter-code interference. The porality of an error signal and a demodulation data series are obtained, which are obtained by selecting either the interference or the difference signal based on the demodulated data series obtained by demodulating the sampling phase and the difference signal. In selecting the residual inter-code interference, the polarity adapting the coefficient is received only when a specific pattern of the demodulation data series is detected update the coefficient only when the demodulated data series is a specific value.
