Abstract
A guard interval length detector is introduced. The guard interval length detector includes a delay conjugate multiplier capable of delaying a plurality of input signals to provide delayed input signals and multiplying each of the plurality of input signals with a complex conjugate of a corresponding one of the delayed input signals to provide multiplied signals, a phase detector capable of determining phase values corresponding to the multiplied signals, and a period detector capable of detecting a period according to the phase values, and determining a guard interval length of the input signals according to the period.
