The subject application is directed to a system and method for content-sensitive document processing. An actuator has a structure such that a striped internal stress distribution is induced within a plane of a bending type actuator of a laminate structure, thereby allowing the actuator to bend so as to constitute a part of a cylindrical shape whose central axis is parallel to the striped direction. The spectrum inversion detector is configured to signal the IQ swap module to swap the in-phase component and the quadrature-phase component when an absolute value of the offset in carry frequency is above a predetermined threshold. In the receive path, a time-domain signal received on the physical baseband is reshaped by the virtual spectrum layer in order to recompose a time-domain symbol in the virtual baseband.
