Error-correction coding can be used to relieve the degradation of bit-error rates (BERs) resultant from the bit-flipping. We propose designs which appropriately integrate deliberate bit flipping and error-correcting codes with unequal error protection. A modified density evolution method is used for obtaining appropriate code degree distributions to our bit-flipping system. Simulation results show that our proposed designs can obtain effective PAPR reduction with very minor BER degradation in many cases. ? 1963-12012 IEEE.Bit error rate; Data communication systems; Error correction; Errors; Frequency division multiplexing; Orthogonal frequency division multiplexing; BER degradation; Degree distributions; Density evolution method; Error correcting code; Error correction coding; PAPR reduction; Peak to average power ratio; Unequal error protections; Codes (symbols)journal article10.1109/TBC.2016.25908202-s2.0-84979740906
