%X <p>The traditional blind symbol synchronization scheme for zero prefix orthogonal frequency division multiplexing (ZP-OFDM) could not acquire accurate symbol synchronization estimation over multipath channels. According to this problem, a new blind symbol synchronization scheme for ZP-OFDM systems was proposed. The proposed scheme is based on zero prefix power collection in the ZP-OFDM symbols whose ZP average power regularly distributes in the two slide windows, and is applied the energy detection method of two unequal length windows to realize the blind symbol synchronization. Simulations show that the proposed symbol synchronization estimation scheme is not only of good estimation precision but also is not influenced by carrier frequency offset over multipath channels.</p>
