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.

Abstract: A low PAPR sequence design method for a wireless communication system includes the following steps: setting relevant parameters of a designed sequence at first, then carrying out multiple iterations, generating multiple length-designated sequences having elements 0 and 1 and obeying the Bernoulli distribution of designated probability density parameters according to the parameters during primary iteration, screening the generated sequences according to the PAPRs of the sequences, updating the parameters of the next iteration based on the screened sequences, and finally mapping the sequence having the minimum PAPR to obtain a sequence with a low PAPR with elements of ?1 and 1 after terminating the iterations. Compared with the prior art, the present invention allows the design of a sequence with a low PAPR with an arbitrary length, and the sequence only contains +1 and ?1 as elements and has good autocorrelation performance.
