摘要： The present invention relates to a method and apparatus for implementing a discrete Fourier transformation (DFT) of a predetermined vector size, wherein at least one enhanced DFT module is provided by using at least one type of DFT module including multiplication by first and second types of twiddle factors in respective different multiplication stages separated by an intermediate integration stage, and generating the enhanced DFT module by combining the at least one type of DFT module with a recursive stage configured to multiply by a third type of twiddle factor and to selectively switch between a bypass function and a butterfly function in said recursive stage. Thereby, an implementation of non 2x-radix Fourier transformation can be achieved with moderate hardware complexity.

摘要： Amorphous ferroelectric materials are formed by a sol-gel type process and the ferroelectric properties stabilized by complete hydrolysis and polycondensation, and extraction of residual organic materials, preferably by heating at temperatures below the temperature at which crystallization may occur. Stable solutions of metal alkoxides are prepared by reacting or dissolving a metal alkoxide in alcohol such as absolute ethanol. The solution may be spincast on essentially any substrate, conductor or nonconductor, crystalline or amorphous, transparent or opaque, and even including plastics. Hydrolysis and polycondensation occur in situ to deposit an amorphous ferroelectric film. Residual alcohol is extracted by heating below the temperature at which crystallization occurs. Such films show P-E hysteresis loops and pyroelectric current. Such ferroelectric thin films are useable in electronic, opto-electronic and optical devices.

摘要： Provided are apparatuses and methods for reducing processor load or power consumption during channel estimation in a receiver. For example, a receiver may monitor a transmission channel and determine if a change in channel parameters or characteristics has occurred. If a change is detected, the receiver may update filter coefficients associated with channel estimation. If a change is not detected, the filter coefficients may be maintained such that no change or updated is made to the filter coefficients.
