Title: Channel profile estimation for OFDM-based communication system
Inventor: SONG KEE-BONG
IPC: H04J11/00
Filed: 2008-05-02
Abstract: A device and method for performing a channel profile estimation for an OFDM-based wireless communication system uses an averaged frequency coherence metric to select a particular channel profile, which is a current channel profile estimate.

Title: A fast-fourier-transform-based (FFT-based) calibration method for analog-to-digital converter (ADC)
Inventor: LEE SHUENN-YUH
IPC: H03M1/10
Filed: 2008-10-24
Abstract: An Fast-Fourier-Transform-based (FFT-Based) calibration method for analog-to-digital converter (ADC) is disclosed. The calibration method can overcome the capacitor mismatch and finite operation amplifier (opamp) gain. The capacitor mismatch and finite opamp gain would let the radix of all the stages not equal to 2n. We can use the FFT processor to evaluate the real radixes of all the stages and use digital method to generate new digital output. Because the method can overcome the finite opamp open loop gain, the specification of the opamp open loop gain is not so critical. That is, we can design the opamp with lower open loop gain to reduce the power dissipation of the pipeline ADC. Moreover, through the FFT-Based calibration technique, the ADC performance can be greatly enhanced.
