| Abstract: | In this paper, we introduce the generation of the primary synchronization signal and its assignment of frequency resources based on ZC sequence for TDD-LTE system. According to the characteristics of DSP, we present the entire functional requirements and design of the scheme for PSCH frequency offset estimation. Finally through the theoretical results, we analyze the frequency offset, which has certain practical significance. |
