PAPR reduction of OFDM systems using H‐SLM method with a multiplierless IFFT/FFT technique
ETRI Journal, Volume 44, Issue 3, Page 379-388, June 2022., 2022 Abstract This study proposes a novel low‐complexity algorithm for computing inverse fast Fourier transform (IFFT)/fast Fourier transform (FFT) operations in binary phase shift keying‐modulated orthogonal frequency division multiplexing (OFDM) communication systems without requiring any twiddle factor multiplications.

State solutions for distribution systems and switching event using a neural network
IET Generation, Transmission &Distribution, Volume 16, Issue 1, Page 71-83, January 2022., 2022 Abstract Power flow calculations are an essential stage in many planning and control applications for distribution systems.To use these in control applications, however, the calculation time needs to be improved, and this can be done by the use of a trained ANN.

Direct processing of mpeg audio using companding and BFP techniques [PDF]
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011 We present techniques for processing MPEG-audio encoded signals during the decoding process, using efficient fixed-point arithmetic operations. A large signal-to-quantization-noise-ratio is achieved over a large range of input levels. By taking advantage of MPEG audio built-in properties, quantization distortion at the outputs of our systems is kept ...
