“…THz communication has unique properties, such as opaque atmosphere, high speed, large capacity, good directionality, small scattering, good security, and high confidentiality. Compared with microwave and optical communications, THz has broad application prospects in long‐distance satellite space communications, large‐capacity short‐distance military confidential communications, and high‐speed wireless security access networks [ 1–14 ] .…”

The use of advanced digital signal processing (DSP) technology in the high‐speed terahertz (THz) communication can effectively compensate the linear and nonlinear effects of the system and further improve the transmission performance of the system. This paper introduces the principle and application of advanced DSP algorithms such as probability shaping (PS) technology, Volterra series nonlinear compensation algorithm, Kramers‐Kronig receiver, look‐up table (LUT) pre‐distortion compensation technology, pre‐equalization and decision‐directed least‐mean‐square equalization algorithm. Combined with DSP algorithms such as PS and LUT pre‐distortion, using photon‐assisted technology to successfully realize the wireless transmission of vector THz signals higher than 1 Tbit/s on the sub‐THz band (D‐band) 4 × 4 multiple input multiple output system.
