On-Chip Implementation Of High Speed And High Resolution Pipeline Radix 2 Fft Algorithm, Rozita Teymourzadeh, Masuri Othman
Dr. Rozita Teymourzadeh, CEng.
A new on-chip implementation of Fast Fourier Transform (FFT) based on Radix 2 is presented. The pipeline and parallel approaches are combined to introduce a new high speed FFT algorithm which increases resolution by using floating point calculations in its structures. The design has the merits of low complexity and high speed performance. Furthermore, latency reduction is an important issue to implement the high speed FFT on FPGA. The proposed FFT algorithm shows the latency of (N/2 log(2) N) + 11. Moreover, this algorithm has the advantage of low mean squared error (MSE) of 0.0001 which is preferable to Radix …
