Abstract
The present invention discloses a time domain pilot design solution suitable for a single-carrier MIMO system. The design solution comprises a time domain pilot location design and a training sequence design. In the present invention, several identical ZCZ sequences are uniformly inserted into each of the data blocks in the same data stream to serve as training sequences, wherein the training sequences inserted into different data streams are different. In addition, the present invention also discloses a simple algorithm for pilot tracking and phase correction suitable for the time domain pilot design solution for the single-carrier MIMO system. The time domain pilot design solution for a single-carrier MIMO system and the algorithm for pilot tracking and phase correction as disclosed in the present invention can improve the performance of a system.
