DEVICE WITH FFT RADIX 2 BUTTERFLY OPERATION PROCESSING ABILITY AND METHOD FOR IMPLEMENTING OPERATIONS THEREFOR

摘要

Have present disclose provides one kind and is capable of handling in 2 butterfly operation of fast Fourier algorithm (FFT) base and its operating method, the device includes at least a latch, plural number, complex adder switch and complex conjugate arithmetic logic unit (ALU). Complex operations unit is disclosed with a simple structure. Parallel processing array can effectively handle carrier and FFT operations by complex operations unit.
