Efficient Selective Mapping PAPR Reduction Technique [PDF]

, 2015
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

Base Station-Driven PAPR Reduction Method Utilizing Null Space for MIMO-OFDM Systems With Amplify-and-Forward Relaying

IEEE Access
This paper proposes a peak-to-average power ratio (PAPR) reduction method that utilizes the null space in a multiple-input multiple-output (MIMO) channel for downlink MIMO-orthogonal frequency division multiplexing (OFDM) signals with multiple-antenna ...

PapR mediated papI repression.

, 2015
(A) β-galactosidase assays were performed with DL1504 strains with and without papI. Induction of PapR using 1mM IPTG resulted in a 50% reduction in β-galactosidase activity in DL1504 (*p-value
