A peak-to-average power ratio reduction method for mixed-numerology multi-carrier systems
In order to support diverse service demands of communication scenarios, 5G adopts the mixed-numerology system based on orthogonal frequency division multiplexing (OFDM).The mixed-numerology systems still have the problem of high peak-to-average power ...

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]
At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

Partial Transmit Sequences for Peak-to-Average Power Ratio Reduction in Multiantenna OFDM
The major drawback of orthogonal frequency-division multiplexing (OFDM) is its high peak-to-average power ratio (PAR), which gets even more substantial if a transmitter with multiple antennas is considered.

PEAK TO AVERAGE POWER RATIO REDUCTION TECHNIQUES
The most extensively used wireless communication system Multiple input multiple affair and orthogonal frequency division multiplexing because of their large benefits and advantages. MIMO OFDM has a major debit which makes the system noisy because of the harpoons in the transmitting signal. Harpoons produce noice and deformation. Different ways are used

An intelligent genetic algorithm for PAPR reduction in a multi-carrier CDMA wireless system
— A novel intelligent genetic algorithm (GA), called Minimum Distance guided GA (MDGA) is proposed for peak-average-power ratio (PAPR) reduction based on partial transmit sequence (PTS) scheme in a synchronous Multi-Carrier Code Division Multiple Access (
