Tap delay adjustment method using beat error rate and tap delay adjustment device using the same

摘要

The present invention relates to a tap delay adjustment method using a bit error rate to prevent a decoding error of a received signal in a fading environment to improve the reception performance of the rake receiver, and a tap delay adjustment device using the same.;The tap delay adjustment apparatus using the bit error rate of the present invention includes a coupling means for supplying and combining signals having respective delay times, a signal strength detecting means for detecting signal strength of a signal having a delay time, and a serial connection to the coupling means. And error correction means for detecting the bit error rate in the signal from the combining means, and control means for selectively varying the delay time in accordance with the value of the bit error rate and the signal strength in common connection with the signal strength detecting means and the error correction means. .;The tap delay adjustment method using the bit error rate and the tap delay adjustment device using the same can reduce the decoding error probability in the fading environment and improve the reception performance of the mobile communication terminal and the base station by adjusting the tap delay to adapt to the fading environment. Can be.
