The use of advanced digital signal pro-cessing(DSP)technology in the high-speed terahertz(THz)communication can effectively compensate the lin-ear and nonlinear effects of the system and further im-prove the transmission performance of the system.This paper introduces the principle and application of ad-vanced DSP algorithms such as probability shaping(PS)technology,Volterra series nonlinear compensation al-gorithm,Kramers-Kronig receiver,look-up table(LUT)pre-distortion compensation technology,pre-equalization and decision-directed least-mean-square equalization al-gorithm.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.
