ABSTRACT:
Provided is an apparatus and method for detecting timing errors based on characteristics of cyclic correlation. The apparatus and method can detect the timing errors of many users by using the cyclic characteristics of a midamble code at a time and detects the timing errors based on the characteristics of cyclic correlation to reduce the time required for detecting the users and lower the complexity in terms of Hardware. The apparatus includes a detection section controller, a register, a midamble generator, a midamble shifter, an accumulator, an adder, a shift register and a timing error detector.
