8PSK is a multiphase shift key modulation and demodulation technology with high-bandwidth efficiency which has great application prospect in the field of high speed data transmission. A simulation study about the Gardner algorithm and the phase and fre-quency detectors ( PFD) algorithm is conducted and the complete structure of symbol timing synchronization and carrier synchronization in 8PSK all-digital demodulator is presented in the paper. The 8PSK all-digital demodulator is designed and implemented by Verilog codes in ISE of XILINX. Finally,the demodulation performance of 8PSK demodulator is tested and the results show that the the demod-ulation loss is less than 1 dB when the BER is equal to 10-6 .
