Abstract:
1. A method for generating a cyclic training sequence with a first training symbol and a second training symbol sequentially, the first training symbol including a first CP and a first information block sequentially and the second training symbol including a second CP and a second information block sequentially, the method comprises: generating randomly the first information block with a length N by a first training symbol information block generator, wherein N is a natural number; copying the last L samples of the first information block to the beginning of the block as the first CP by a first CP generator, wherein L is a natural number less than N; generating the second information block with the length N by the first information block of the first training symbol in a circle manner in which the last d samples of the first information block are shifted to the position before the rest (N−d) samples and the N samples thus rearranged forms the second information block by a second training symbol information block generator, wherein the corresponding relation between the first and second information blocks is the structure characteristic of the cyclic training sequence, and d is 0 or any natural number less than N; and copying the last L samples of the second information block to the beginning of the block as the second CP to form the integrated cyclic training sequence by a second CP generator.
