AI Technical Summary
Existing integrated waveforms have shortcomings in terms of communication rate and spectral efficiency, especially when LFM signals are amplitude modulated, the communication rate is low, and when angle modulated, the spectral efficiency is low.
By applying DC bias processing to the communication sub-signals, encoding the sensing subcarriers, generating a single-carrier sensing integrated waveform, and then using frequency conversion processing to make the spectra of adjacent single-carrier sensing integrated waveforms overlap, forming a multi-carrier sensing integrated waveform, while preserving the unique phase of the sensing sub-signals, high communication rate and high spectral efficiency are achieved.
It achieves high communication rates and high spectrum efficiency, and improves sensing accuracy and spectrum utilization by sharing time and frequency resources and hardware equipment.
