Abstract
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.
