Design of synchronization sequences in a MIMO demonstration system
Guangqi Yang, Wei Hong, Haiming Wang, Nianzu Zhang · 2005
MIMO (multi-input and multi-output) wireless communication systems have attracted serious research interest since 1990. It is well accepted that MlMO is a way to breakthrough the wireless capacity bottleneck. However, as the antenna number of a MIMO system increases, the complexity of the system increases dramatically. In a M /spl times/ N (M transmitting antennas by N receiving antennas) MIMO system, the receiver have to perform the synchronization on M /spl times/ N channels which requires huge computing resource. Synchronization design is one of the great challenges in the design of MIMO systems. This paper presents the synchronization design of a 4 /spl times/ 4 MIMO demonstration system. In the design, Golay complementary pairs are used to construct the synchronization sequences.
