AI Technical Summary
In fifth-generation mobile communication technology (5G) and future communication systems, orthogonal frequency division multiplexing (OFDM) systems have the problem of excessively high peak-to-average power ratio (PAPR), which leads to signal distortion and low spectral efficiency, especially in the development of 6G with higher frequency bands and larger bandwidth.
By using a resource mapping method, including information exchange between receiving and transmitting nodes, and processing the signal with a phase rotation factor sequence, the peak-to-average power ratio (PAPR) of the signal is reduced. This method is applicable to 5G and 6G mobile communication systems.
It reduces the PAPR of the communication system, improves the overall performance and spectral efficiency of the communication system, and reduces signal distortion and nonlinear operation of the power amplifier.
