英文摘要	A discrete SIFT processor for real-time spectrum analysis is proposed. To overcome the drawbacks of previous discrete STFT algorithms and architectures, a new architecture based on FFT array is presented. By exploiting the symmetry of window function, multipliers for window multiplication can reduce to N/2. And the utilization rate of the multiplier in FFT processing unit can be improved by introducing switch arrays. The design has been synthesized using SMIC 0.18um standard cell library using a Verilog model. After placed and routed, static timing analysis and dynamic simulation with timing back annotated show that under worst-case conditions, 180MHz clock rate can be achieved, which means that the real time spectrum analysis demand can be fulfilled under the same sample rate.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000246793200485&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Hardware & Architecture; Engineering, Electrical & Electronic; Telecommunications; EI; CPCI-S(ISTP); 1
