RADIO ACCESS MODULE EMBODIED AS EPLD

摘要

PURPOSE: A radio access module embodied as an EPLD(Embedded Programmable Logic Device) is provided to be simply embodied and reduce the number of components by coding the function of the radio access module by using a VHDL(Very High speed integrated Circuit hardware Description Language) in an IS(Interim Standard)-95C BTS(Base station Transceiver Subsystem) and being embodied as the EPLD. CONSTITUTION: An EPLD(30) is embodied by coding the function of a radio access module using a VHDL. A ROM(22) stores an operation program necessary for driving the EPLD(30). A UDC(Up Down Convert)-FEU(Front End Unit) interface unit(21) interworks with an EPLD, reads state information of the UDC and the FEU, sets a PLL(Phase Locked Loop), and controls an attenuation value on a transmission and reception path.
