摘要：
This paper presents a novel method for enabling communication in cyclostationary interference limited environments by adaptively inserting and exploiting spectral redundancy in an orthogonal frequency division multiplexing (OFDM) signal. The redundancy is formed through repeating data symbols across OFDM symbols in both time and frequency. A novel frequency shift (FRESH) filter is applied to exploit the time-varying cyclostationary properties, enabling the communication while under interference. The ability to design an interference mitigating property into the communication signal creates a new degree of freedom when optimizing and adapting a waveform's parameters. Simulation results demonstrate the performance gains in both signal to interference and noise ratio (SINR) and bit error rate (BER) as compared to traditional time-invariant optimal filtering techniques and error correcting codes (ECC).
