Abstract
The disclosure involves a method and an apparatus for implementing preamble generation. The method comprises: obtaining a first parameter value according to a root sequence number of a Zadoff-Chu (ZC) sequence; obtaining an initial value of a first sequence, according to a length and a cyclic shift value of the ZC sequence and the obtained first parameter value; performing iterative calculations on the first sequence according to the initial value of the first sequence and the first parameter value; performing iterative calculations on a second sequence according to the iteratively calculated values of the first sequence and a preset initial value of the second sequence; performing Discrete Fourier Transform (DFT) on the iteratively calculated values of the second sequence. The method and apparatus in the disclosure can achieve low complexity and high calculation precision in the calculation process and greatly reduce the amount of calculation and storage.
