Noise elimination method and apparatus |
| abstract |
In a noise elimination method and apparatus, a spread spectrum modulation signal having a data signal and an overlapping noise component at a signal point on a time axis and a noise component at a zero point on the time axis is received. A correlation of the received modulation signal to a spread spectrum code is generated by using a correlating filter. Zero is set at points of the modulation signal other than the signal point where the correlation becomes the maximum, so that the noise component at the zero point is extracted from the modulation signal. The noise component at the signal point is predicted by performing interpolation prediction based on the extracted noise component. The noise component at the signal point is removed from the modulation signal based on the predicted noise component. |
