Algorithms for the Encoding and Reception of OFDM Signals Based on Manipulation with Minimum Frequency Shift

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.
