Embodiment Construction
[0053] In the embodiment of the present invention, a plurality of mutually different long complementary Golay sequence pairs are generated from a short complementary Golay sequence pair and transmitted through different transmitting antennas, which is applicable to a distributed multi-antenna system, and the generated complementary Golay sequences are less correlated with each other. Well, the delay and frequency offset estimates are accurate.
[0054] Such as figure 1 As shown, it is a flowchart of an embodiment of a method for sending synchronization information in the present invention, which includes the following steps:
[0055] Step 101, generating multiple groups of different long complementary Golay sequence pairs based on the short complementary Golay sequence pairs.
[0056] Step 102, selecting a long complementary Golay sequence pair from multiple sets of mutually different long complementary Golay sequence pairs and assigning it to each transmitting antenna.
