Abstract_FL	To solve the problem of low transmission efficiency caused by the high overhead of the pilot in the short packet structure,a M-ary overmodulation based on cyclic shift symbol for pilot-free short packet communication scheme was proposed.The scheme adopted cycle code shift keying(CCSK)to modulate pseudo noise(PN)sequences,and used M-ary overmodulation sequences to perform secondary modulation on multiple CCSK symbols.The receiving end uti-lized the good autocorrelation and cross-correlation characteristics of PN sequences to achieve pilot-free detection and synchronization,which effectively eliminated the training overhead of short packet pilots.The introduction of overmodu-lation effectively improved symbol synchronization performance while carrying additional information.The synchroniza-tion evaluation function of short packet symbols after CCSK and overmodulation was derived,and the feasibility of M-ary overmodulation loading information was verified.Simulation results demonstrate that under AWGN and Rayleigh fading channels,the proposed M-ary overmodulation based on cyclic shift symbols for pilot-free short packet communi-cation scheme for pilot-free short packet communication effectively improves the symbol synchronization performance,and transmits additional lbM bit information compared to a single overmodulation sequence.
