    摘要

    In this paper, a detection and estimation scheme and its architecture design for synchronization in 60 GHz indoor wireless transmission are presented. With the complementary Golay sequence based preamble structure, the proposed synchronization scheme is designed to detect the preamble and symbol boundary, estimate the frequency offset within a unified architecture. For the very high sampling speed at 60 GHz transmission, the architecture is designed as 8×-parallelism with feed-forward data path. This architecture supports the single carrier (SC) and orthogonal frequency-division multiplexing (OFDM) transmissions of both IEEE 802.15.3c and IEEE 802.11ad standards. The synchronization module is implemented as a part of a digital baseband receiver for IEEE 802.15.3c. The tolerance of maximum frequency offset is about 114.58 ppm and 171.87 ppm for SC and OFDM mode, respectively. The implementation result shows that it takes about 0.84 mm2 of area (equivalent to 307 k gate counts). The power consumption is about 59 mW in SC mode and 96 mW in OFDM (HSI) mode when operating at 1.76 GHz and 2.64 GHz chip rate, respectively.
