Beamforming and PAPR Reduction for MISO-OFDM Systems [PDF]
A peak-to-average power ratio (PAPR) reduction technique for multi-input single-output (MISO) orthogonal frequency division multiplexing (OFDM) systems with beamforming is proposed. This technique consists of adaptive antenna selection and phase rotation.

The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Efficient Selective Mapping PAPR Reduction Technique
OFDM is a form of multicarrier modulation technique with high spectral efficiency and immunity to interference. One major drawback of OFDM systems is the high peak to average power ratio (PAPR) which leads to power inefficiency and signal distortion with

We propose a Doppler‐tolerant DFT‐spread orthogonal time‐coded OFDM (DSS‐OTC‐OFDM) waveform for MIMO radar that maintains orthogonality under Doppler shifts while enabling flexible code design. An optimisation framework is developed to minimise peak sidelobe level (PSL) and suppress cross‐correlation after matched filtering across a range of Doppler ...

Reduced Complexity SLM Method for PAPR Reduction
In this paper, the computational complexity will be reduced using a revised version of the selected mapping (SLM) algorithm. Where a partial SLM is achieved to reduce the mathematical operations around 50%. Although the peak to average power ratio (PAPR)
