Integrated sensing and communication (ISAC), a key technology for next-generation wireless networks (e.g., 5G-A 6G), aims to provide both large-capacity high-resolution microwave sensing/ranging simultaneously. Microwave photonics (MWP)-ISAC, with its unique features such as high frequency, large bandwidth, low frequency-dependent loss, flat frequency response, fast analog signal processing, strong immunity electromagnetic interference, offers superior performance in terms of data rate...
A microwave photonics deceptive RF regeneration method with multi-characteristic regulatory is proposed for radar jamming. In this scheme, Doppler frequency shift (DFS) implemented by a Serrodyne structure based on the modulation of sawtooth wave signal. This can effectively fulfill small original carrier through carrier-suppressed single sideband without any filter, which makes possible wideband radio The phase shifting signal achieved adjusting bias voltage modulator. pulse stored in an...
Multifunctional integration of electronic equipment is a main development trend in the future, wherein integrated signal generation enables key part. Therefore, it great significance to develop anti-jamming joint radar-communication (JRC) signal. Here, photonics-assisted scheme millimeter-wave (MMW) JRC proposed. A large-bandwidth MMW dual-band agile generated based on photonic up-conversion and frequency permutation techniques. Meanwhile, thanks radar de-chirping combined with coherent...
An adaptive delay calibration method for optical beamforming networks (OBFN) based on wideband sweep and windowed FFT spectrum analysis is proposed demonstrated by simulation. With the of signal, difference between different channels in OBFN can be obtained continuously, canceled adaptively controlling variable lines(VODL), resulting fast high precision an OBFN. Furthermore, assisted pilot carriers with multiple frequencies, phase unwrapping achieved, beyond 2π compensated. In order to...
We experimentally demonstrated the use of intelligent impairment equalization (IIE) for microwave downconversion link linearization in noncooperative systems. Such an equalizer is realized based on artificial neural network (ANN). Once training process completed, inverse transfer function can be determined. With transformation detected signal after transmission, third-order intermodulation distortion components are suppressed significantly without requiring any prior information from input...
