US Patent 7760810 Receiver and method for digital multi carrier transmission

A receiving apparatus and method for compensating a clock-inconsistency between a transmitter and a receiver for a digital wavelet multi-carrier transmission. First and second wavelet transforms of received data are performed to output first and second transformed data and then a complex data generator generates the complex data by defining the first transformed data as in-phase components of complex information and the second transformed data as orthogonal components of the complex information and the complex data is output. Subsequently, an equalizer equalizes the complex data and outputs an equalized complex data a clock-inconsistency compensator compensates A clock-inconsistency between a receiver and a transmitter by using a result of a decision and the equalized complex data, and outputs a compensated complex data. A decision unit decides the compensated complex data, and outputs a result of the decision.
