The Research on the FDD-LTE System and its Key Technologies
Abstract:
The paper elaborates OFDM technology and its advantages and disadvantages, analyzes the basic principles on random access preamble sequence design ,and defines and analyzes Zadoff sequences and its excellent characteristics . After that, the paper analyzes the frequency offset exists and ZC sequence cyclic shift for the reasons for the decline of the autocorrelation peak of Zero, as a relative frequency offset .Finally,the paper proposes and emphasizes on the design of random access preamble sequence.
