Joint radar communication system design based on filter bank multicarrier modulation scheme

IET Radar, Sonar & Navigation, 2023
Since orthogonal frequency division multiplexing (OFDM) signals are sensitive to Doppler shift, OFDM signals with cyclic prefix (CP) not only reduce the communication rate but also result in symmetric pseudo peaks in the ambiguity function of the radar ...

Joint waveform design of radar detection, wireless communication and jamming based on chaotic composite modulation

Electronics Letters, Volume 60, Issue 18, September 2024.
In the current most powerful filter‐bank multi‐carrier comb spectrum framework, a parameter‐agile time–frequency structure between symbols is elaborated to improve the uncertainty of waveform generation architecture. Furthermore, a novel composite modulation strategy that combines intra‐symbol chaos‐based radar frequency modulation and inter‐symbol ...
