The invention discloses a distributed
MIMO (
Multiple Input Multiple Output) integrated
system and method based on a reconfigurable notch
chaotic optoelectronic oscillator, belongs to the field of
microwave photons, and solves the problems of spectrum resource conflict, difficulty in multi-node synchronization, discrete
inductance functions and the like. According to the
system, a plurality of independent
chaotic OEOs are combined with an
optical frequency comb to drive an FIR filtering effect,
MIMO chaotic signals with reconfigurable notch frequency points and quantity are generated, and dynamic allocation of spectrum resources is realized. The notch
frequency band is used as a
communication channel embedded modulation
signal, and supports multi-
spectrum sharing with 2.4 G, 5G, Wi-Fi and the like; a non-notch
frequency band is reserved as a
radar signal, and the range resolution is improved by using the
broadband characteristic of the chaotic waveform. The star topology optical network expands the coverage area of a distributed
system, and a centralized
processing architecture reduces the complexity of multi-node
collaboration. The invention provides an integrated solution of high-precision environment
perception and high-reliability communication for smart cities, Internet of Vehicles and the like, and is suitable for dense urban areas with resource shortage and dynamic multi-service environments.
