摘要翻译：
基于正交频分复用的M进制频移键控（OFDM-MFSK）是一种将MFSK与OFDM波形相融合的非相干调制方案。它是为了在信道估计非常困难的恶劣环境中提高接收机的灵敏度而设计的。本文提出了OFDM-MFSK作为智能计量技术，并对其性能进行了测试，并与普通OFDM-BPSK进行了比较。我们的结果表明，OFDM-MFSK的分组误码率(PER)显著提高，取决于MFSK大小值(M)。另外，自适应OFDM-MFSK选择最佳M值，使每个智能电表(SM)具有最小的PER和更高的吞吐量，比OFDM-BPSK具有更好的覆盖范围。虽然它的吞吐量和容量低于OFDMBPSK，但每个扇区连接的SMs更高。基于智能计费技术的要求，即网络和短消息之间需要高覆盖和低数据量的要求，OFDM-MFSK可以有效地应用于该技术。

英文摘要：
  The Orthogonal Frequency Division Multiplexing based M-ary Frequency Shift Keying (OFDM-MFSK) is a noncoherent modulation scheme which merges MFSK with the OFDM waveform. It is designed to improve the receiver sensitivity in the hard environments where channel estimation is very difficult to perform. In this paper, the OFDM-MFSK is suggested for the smart metering technology and its performance is measured and compared with the ordinary OFDM-BPSK. Our results show that, depending on the MFSK size value (M), the Packet Error Rate (PER) has dramatically improved for OFDM-MFSK. Additionally, the adaptive OFDM-MFSK, which selects the best M value that gives the minimum PER and higher throughput for each Smart Meter (SM), has better coverage than OFDM-BPSK. Although its throughput and capacity are lower than OFDMBPSK, the connected SMs per sector are higher. Based on the smart metering technology requirements which imply the need for high coverage and low amount of data exchanged between the network and the SMs, The OFDM-MFSK can be efficiently used in this technology.
