Sequence with a low PAPR design method for wireless communication system

A computer-implemented method for providing low Peak to Average Power Ratio (PAPR) sequence design for a Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system, the sequence with a low PAPR only contains elements −1 and +1, wherein the computer-implemented method comprises the following steps:

• setting relevant parameters of a designed sequence at first, wherein multiple iterations are executed until conforming to a termination condition,
• generating multiple length-designated sequences having elements of 0 and 1 and obeying the Bernoulli distribution of designated probability density parameters according to the parameters during primary iteration,
• screening the generated sequences according to the PAPRs of the sequences, wherein a minimum PAPR is electronically selected, wherein a threshold of the PAPR is electronically set and is used for screening the generated sequences,
• updating the parameters of the next iteration based on the screened sequences,
• mapping the sequence having the minimum PAPR to obtain a sequence with a low PAPR with elements of −1 and 1 after terminating the iterations, and
• transmitting or receiving wireless signals based on at least a portion of the sequence with the low PAPR via the OFDM wireless communication system.
