Abstract: A huge shortcoming of orthogonal frequency division multiplexing (OFDM) is the extreme peak-to-average power ratio (PAPR) of the transmitted signals. Partial transmit sequence (PTS) method is capable of enhancing PAPR statistics of OFDM signals. In PTS method, data block to be forwarded is split into disjointed sub-blocks and the sub-blocks are merged through usage of phase factors for minimising PAPR. Because generic PTS needs extensive search over every combination of permitted phase factors, search complexity rises in an exponential manner with quantity of sub-blocks. In the current work, a novel sub-optimal technique on the basis of binary honey bee mating (BHBM-PTS) protocol is suggested for searching better combination of phase factors. BHBM-PTS protocol may considerably decrease computation complexity for bigger PTS sub-blocks and provides lesser PAPR simultaneously. Simulations prove that BHBM-PTS protocol is an effective technique for achieving considerable PAPR decrease.
