A modified cross antenna rotation and inversion algorithm for Peak-to-Average Power Ratio Reduction in MIMO-OFDM systems

In this work, a Modified Cross Antenna Rotation and Inversion algorithm is introduced to reduce the high Peak to Average Power Ratio (PAPR) of the MIMO-OFDM signals. Cross Antenna Rotation and Inversion (CARI) and its derivative (SS-CARI) are considered to be very effective methods to reduce high...
