A short training sequences for orthogonal frequency division multiplexingpassive optical network (OFDM-PON) symbol synchronization is proposed. By adjusting the subcarrier allocation scheme of short training sequence in a wireless local area networks (WLAN), the mean of short training sequence signal in time domain is made from non-zero to zero, overcoming interference of receiving data demodulation caused by the wrong trail of the non-zero mean short training sequence in the time-domain. Simulation and experiments on data demodulation show that the improved method can effectively reduce training sequence interference errors caused by tailing.
