The proposed architecture also presents a refreshing approach to minimise error due to the finite word-length in the output windowed spectrum compared with the existing method. The architecture can also be extended for other high order generalised cosine windows such as Blackman, Blackman–Harris, and flat-top. The post-route results on the Virtex-6 FPGA as well as the physical ASIC post-layout results are also presented for the proposed architecture.}, title = {CORDIC-based Hann windowed sliding DFT architecture for real-time spectrum analysis with bounded error-accumulation}, journal = {IET Circuits, Devices & Systems}, issue = {5}, volume = {11}, year = {2017}, month = {September}, pages = {487-495(8)}, publisher ={Institution of Engineering and Technology}, copyright = {© The Institution of Engineering and Technology}, url = {https://digital-library.theiet.org/;jsessionid=4rad0itofiga7.x-iet-live-01content/journals/10.1049/iet-cds.2016.0375} }
