摘要：
This paper presents a novel 128-point Fast Fourier Transform (FFT) processor for practical Ultra-wideband (UWB) applications. The pipeline FFT processor based on the proposed non-Cooley-Tukey radix-8 unit can provide high throughput rate and has low hardware complexity. The radix-8 unit's hardware cost can save up to 20% compared with Radix-2 Single path Delay Feedback (R2SDF) architecture. Furthermore, both the input and output are In nature order. A 128-point FFT processor has been designed and implemented with SMIC 0.18 mu m CMOS process based on the proposed architecture. The throughput rate of proposed FFT processor is up to 409.6 Msample/s, which can meet the specification of UWB systems.
