چکیده

In this paper, a scaling method for large pipelined FFT implementations is proposed. Compared to existing block scaling methods, like implementations of Convergent Block Floating Point (CBFP), the memory requirements can be reduced while preserving the SNR. The FFT processor is implemented in a 0.35μm standard CMOS technology and is capable of calculating a 2048 complex point FFT or IFFT in 40μs with a maximum clock frequency of 50MHz.

A High Performance Pipelined Discrete Hilbert Transform Processor

A high performance pipelined discrete Hilbert transform (HT) processor is presented in this paper. The processor adopts fast Fourier transform (FFT) algorithm to compute discrete HT. FFT is an effectively method to compute the discrete HT, because the discrete HT can be calculated easily by multiplication with +j and -j in the frequency domain. The radix-2 FFT algorithm with decimation-in-frequ...
