On the performance of Hirschman Optimal Transform Pre-coded UFMC for
reduction of PAPR
Universal filtered multi carrier (UFMC) system is considered to be the
best choice for 5G waveform when compared with orthogonal frequency
division multiplexing (OFDM), filtered OFDM (f-OFDM), filter bank multi
carrier (FBMC) and generalized FDM (GFDM) in terms of spectral leakage,
complexity and compatibility with 5G. The all multi carrier systems are
suffers from high peak to average power ratio (PAPR) causes non linear
functioning in receiver. In this paper, we proposed a Hirschman optimal
transform (HOT) based pre-coding for reducing the PAPR in UFMC systems.
Results reveals that HOT pre-coded UFMC promising less PAPR compared
with discrete cosine transform (DCT), discrete Hartley transform (DHT)
and discrete sine transform (DST) and discrete Fourier transform (DFT).
