In this work, a new symbol time synchronization and its architecture design for high-throughput millimeter wave systems based on orthogonal frequency-division multiplexing (OFDM) are introduced. Complementary Golay sequences with good signal properties are popular training sequences used for the preamble design of a multi-gigabit communication system, which is the promising technology for future 5G communications. The basic idea of our contribution is to obtain a time estimate based on the aperiodic autocorrelation function (ACF) of complementary Golay sequences. Besides, achieving low power consumption and less chip area remains the challenge of high-throughput millimeter wave systems. To achieve over 2.64 GSamples/s throughput requirement, the proposed algorithm is especially suitable for the parallel design architecture of very high throughput receivers. Moreover, the complexity is further reduced by employing the correlation characteristic of the ACF of complementary Golay sequences and the regularity of the algorithm. Simulations confirm the advantages of the proposed synchronizer.
