On performance of LTE UE DFT and FFT implementations in flexible software based baseband processors
The use of the Fast Fourier Transform (FFT) and the Discrete Fourier Transform (DFT) in the physical layer implementations of the latest cellular and wireless standards such as Long Term Evolution (LTE) is highly common place. Given that FFT and DFT algorithms consume a significant percentage of the processing power of a baseband processor, it is important to implement these algorithms with close attention to the underlying architecture of the platform for which they are being developed.
