Waveform Design and Accurate Channel Estimation for Frequency-Hopping MIMO Radar-Based Communications

Waveform Design and Accurate Channel Estimation for Frequency-Hopping MIMO Radar-Based Communications

Frequency-hopping (FH) MIMO radar-based dual-function radar communication (FH-MIMO DFRC) enables communication symbol rate to exceed radar pulse repetition frequency, which requires accurate estimations of timing offset and channel parameters. The estimations, however, are challenging due to unknown, fast-changing hopping frequencies and the multiplicative coupling between timing offset and channel parameters. …
