Abstract: A signal delay time estimation device in a mobile communication system and a method thereof are provided to estimate delay time insensitive to signal properties by carrier combination, and to estimate delay time insensitive to distortion exactly by an amplifier when a digital predistorter is used, thereby increasing estimation accuracy of signal delay time. A first preprocessor(110) calculates amplitude of the first and second signals included in plural signals, and attenuates RF(Radio Frequency) signals. A sample delay estimator(130) calculates correlation coefficients by comparing the first signal outputted from the first preprocessor with the second signal outputted in a sample unit. A second preprocessor(150) clips the outputted first and second signals. A sub sample delay estimator(170) estimates delay time by comparing time differences between the first signal and the clipped second signal based on the clipped first signal sub sample unit.

Abstract: PURPOSE: A method for estimating an LS(Least Squares) carrier frequency error, an estimator therefor, a transmission diversity system using the same, and a transceiver for a 3GPP(3rd Generation Partnership Project) system are provided to have an excellent performance in a time-varying channel without any information about a channel. CONSTITUTION: A Rayleigh channel(10) receives a certain value and outputs the received certain value. A multiplier(20a) multiplies the output of the Rayleigh channel(10) by a value. An adder(30a) adds a value((n)t) to the output of the multiplier(20a). A receiving filter(40) cancels a noise included in the output of the adder(30a).
