Abstract
Multi-h CPFSK mapper in an OFDM system can offer significant gain in both PAPR and bit error rate probability. The OFDM PAPR problem is addressed and investigated using SLM reduction technique. Next, an OFDM system with a multi-h CPFSK mapper is considered and its performance is evaluated in terms of the upper and lower bounds on bit error rate probability, and a closed form expression is obtained. Also, the system performance is examined over Rayleigh and Nakagami-m fading channels. The simulation and analytical results show that the performance of the system is superior than the OFDM system with BPSK and single-h CPFSK mappers.
