摘要： A method and apparatus for estimating a signal delay between a transmission signal which is to be processed in a predetermined communication device of a mobile communication system, and a feedback signal. Each of the transmission and feedback signals is sampled for a predetermined length, and signal power magnitude values are computed in a sample unit and are stored in first and second memory blocks. Mean squared error (MSE) values are computed from a plurality of samples, while a start sample position of one block is shifted on a basis of a start sample position of the other block. A sample delay value is estimated from a start sample position of the one block with a smallest MSE value such that a sample delay between a transmission signal and a feedback signal is closely estimated regardless of a frequency allocation (FA) value.

摘要： A digital predistortion apparatus is provided for predistorting a nonlinear characteristic caused by a wideband power amplifier that amplifies a input signal. The digital predistortion apparatus includes a predistorter, connected to the power amplifier via a digital-to-analog converter (DAC) and a frequency up-converter, for receiving the input signal and compensating for the nonlinear characteristic using a look-up table that depends upon a change in output power of the power amplifier. The digital predistortion apparatus further includes look-up table (LUT) updating block for adaptively updating the look-up table by comparing a feedback signal output from the power amplifier, connected thereto via an analog-to-digital converter (ADC), with the input signal output from the predistorter.
