Abstract: A variable focal length lens consists of many micromirrors with degrees of freedom rotation and/or degrees of freedom translation and actuating components. As operating methods for the lens, the actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the variable focal length lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors. The lens can correct aberration by controlling each micromirror independently. The lens can also be of a desired arbitrary shape and/or size. The micromirrors are arranged in a flat plane or in a curved plane with a predetermined curvature. The electrodes determining the position of the micromirrors can be made of material with high electrical conductivity, preferably metal.

Abstract: An apparatus and method for transmitting uplink fast feedback information using a fast feedback channel in an orthogonal frequency division multiple access (OFDMA) communication system. A channel encoder generates uplink fast feedback information to be transmitted, and outputs codewords designed such that a minimum Hamming distance between the codewords is maximized, according to the uplink fast feedback information. A non-coherent modulator performs orthogonal modulation on transmission symbols corresponding to the codewords and allocates the orthogonal-modulated transmission symbols to subcarrier cluster. An inverse fast Fourier transform (IFFT) block performs IFFT on a transmission signal having the subcarrier cluster and transmits the IFFT-processed transmission signal.
