| Abstract: | For the LTE system,secondary synchronization signal detection algorithm complexity is a big problem.According to the characteristics of auxiliary synchronous signals,this paper proposed a detection method based on Hadamard transform.Derived in detail the theoretical basis of this detection approach,and compared to regular method,then came to the conclusion that this scheme can reduce 90 percent computation.Finally through MATLAB simulation,confirmed this method can obtain the same detection performance as t... |
