We presents a noise suppression method for noisy factory environment. The proposed algorithm (Step 1)determine the voise signal or the noisy signal using the correlation of received signal in noisy factory environment, (Step 2)estimate the noise variance using spectral subtraction, and (Step 3) perfom the colored driving source type Kalman filter. The characteristic of this method is (1) Real-time processing and (2) high performance noise suppression. Numerical example show the effectiveness of proposed algorithm using TI DSP borad. |
