| Abstract: | A DSP RF ASIC scheme for GFSK quadrature modem is introduced. After a review of implementation methods for traditional GFSK modems, the base band scheme of a GFSK quadrature modem is analyzed, and the system simulation for GMSK modem on the SYSTEMVIEW software platform is discussed. The simulation algorithm is then applied to TI VC5402 DSP. In the hardware environment of RF ASIC subsystem chips U2793B and AD6459, the quadrature modem function is implemented satisfactorily. |
