Abstract :
Recent advances in electronic technology integration coupled with increasing needs for more services in portable communications favors the development of high performance dual-mode terminals. We present the complete architecture implementation of the GMSK/GFSK modulator/demodulator including the FIR filters design. The main features of the modulator/demodulator and the architectural implementation of FIR filters are described. The interface with ASPIS processor and A/D & D/A converters is also described in detail manner. The whole architecture of the modulator/demodulator was described by VHDL hardware language, synthesised and implemented in Xilinx environment
