Abstract
Systems and methods are described for providing a reconfigurable circuit having multiple distinct circuit configurations with respective distinct operating modes The circuit may be controllably configures to perform a fast Fourier transform function, a multiplier function, and a divider function. In one exemplary practical application of the invention, the fast Fourier transform function, multiplier function, and divider function may be used for signal demodulation, channel equalization and channel estimation for a WLAN IEEE 802.11 system.
