| Abstract: | Sounding reference signal is used for the uplink channel quality measurements in TD-LTE system.At beginning, this paper provides the various formulas that generating the SRS,and then gives the design flow chart for programming realization. After that,use TI TMS320C6455 DSP to generate SRS by software programming,definitely speaking,by using C and Assembly ianguage. Finally,this paper specifically describe the realization of division and exponentiation because it's the hardest and most time-consuming operations in the DSP implementation.The method written in this paper has been applied to LTE-TDD wireless integrated test instrument development. |
