A Method of Improving the Correlation Properties of OFDM Chirp Waveform Diversity
IEEE Geoscience and Remote Sensing Letters(2021)
摘要
In this letter, an orthogonal frequency-division multiplexing (OFDM) chirp waveform diversity design scheme is proposed to achieve better correlation properties. First, the subchirp duration and bandwidth are optimized simultaneously to increase the degree of freedom in waveform diversity. Second, an optimization procedure is proposed based on the idea of Gram–Schmidt orthogonalization. To reduce ...
