    Abstract: A method and pre-corrector for correcting signals in radio frequency links are provided. The method comprises: obtaining, in a time division order, a set of pre-distortion vectors for the respective radio frequency links by using one and the same set of pre-distortion vector obtaining means based on difference in arrival time of cyclic delay frames in the respective radio frequency links of a multiple input multiple output (MIMO) system; and correcting a subsequent signal in the respective radio frequency links by using the set of pre-distortion vectors corresponding to that radio frequency link. With the present invention, it is only required to scan a frame header once to generate an error vector table for the input signal across the entire dynamic range of power. The device can be reused by utilizing the cyclic delay frame structure, so as to achieve high linearity of a radio frequency header.

  • Patent number: 7486430
    Abstract: In a 3D free space micromirror device, a mirror plate is joined with actuators through flexible springs where the other ends of the actuators have fixed support on the substrate. Single crystal silicon and aluminum are used as bi-morph materials with silicon dioxide providing electrical isolation between the two. Thickness variation in the microstructure is achieved by two-step p-n junction formed in a p-type substrate. Thick and thin n-silicon layer formation and DRIE cut mechanisms are employed in such a way that all the thick and thin silicon components of the structure are released simultaneously avoiding overetch which can be detrimental to the thin flexural springs. Working prototypes of the device have been found suitable for any optical switching array architecture where deflections up to 10 degrees are required.
