The developed algorithms for the encoding and reception of OFDM signals using minimum frequency shift keying (OFDM-MSK signals) are considered and investigated. OFDM-MSK signals have low out-of-band power compared to OFDM signals using phase shift keying. It is shown that the developed algorithms for the encoding and reception use a lattice structure of signals with a continuous phase with a minimum frequency shift in combination with a productive algorithm for fast spectral transformation in the Fourier basis.

基于最小频移操纵的OFDM信号编码和接收算法

考虑并研究了使用最小频移键控（OFDM-MSK信号）对OFDM信号进行编码和接收的算法。与使用相移键控的OFDM信号相比，OFDM-MSK信号具有较低的带外功率。结果表明，用于编码和接收的已开发算法将具有最小频移的具有连续相位的信号的晶格结构与用于傅立叶基础上的快速频谱变换的有效算法相结合。
