摘要

OFDM系统中的多h CPFSK映射器在PAPR和误码率概率方面都有显著的提高。利用SLM降频技术对OFDM的PAPR问题进行了研究。其次，考虑了具有多h CPFSK映射器的OFDM系统，并从误码率概率的上界和下界对其性能进行了评价，得到了一个封闭的形式表达式。此外，还测试了系统在瑞利和Nakagami-m衰落信道下的性能。仿真和分析结果表明，该系统的性能优于带有BPSK和单h CPFSK映射器的OFDM系统。

PAPR and BER performance analysis of OFDM system with multi-h CPFSK mapper

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.
