Title: Interference removing part, radio terminal equipment and method for removing interference
Inventor: YOKOYAMA MITSUO
IPC: H04B1/7107
Filed: 2001-02-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to build a circuit in a portable terminal by simplifying the circuit and to easily remove an interference signal from a signal of another channel. SOLUTION: A multiplier 3 multiplies a spread spectral signal received from an antenna 1 by the carrier of a required signal outputted from a synchronizing circuit 2. A multiplier 10 multiplies a receiving signal from a sampling circuit 9 by the diffusion code of the required signal outputted from the circuit 2. An adaptive filter part 7 obtains a synthetic signal concerned with a non- required signal by executing multiplication and synthesis on the basis of a tap coefficient applied from a tap coefficient control circuit 6 and a signal outputted from the circuit 9. A subtracter 8 subtracts an output of the filter part 7 from an output of the multiplier 10 to obtain a required receiving signal. A comparator 12 outputs an error signal having a difference between the input and output of a limiter 11.  The control circuit 6 outputs the tap coefficient and controls the tap coefficient on the basis of the output from the comparator 12.
