Sistem Global untuk Komunikasi Mudahalih (GSM) merupakan rangkaian komunikasi digital bersel yang digunakan oleh kebanyakan negara di seluruh dunia. Telefon mudahalih GSM mula digunakan pada tahun 1991 dan menggunakan pelbagai pengesan dan pembetul ralat dalam system perhubungan untuk meningkatkan kualiti perkhidmatan. Oleh itu, kajian telah dijalankan ke atas enam bahagian pengekod dan enam bahagian penyahkod dalam system perhubungan telefon mudahalih GSM bagi menghasilkan cipset dengan menggunakan VHDL. Sistem perhubungan ini penting bagi mengesan dan membetulkan ralat serta melindungi data suara semasa penghantaran dan penerimaan. Perisian Xilinx ISE 7.1i bentuk VHDL digunakan sebagai peralatan utama dalam kajian ini kerana ia membolehkan setiap bahagian pengekod dan penyahkod dimodel, disintesis, disimulasi dan seterusnya dilaksana sebelum dimuat turn ke atas peranti Field Programmable Gate Array (FPGA) iaitu Spartan3 XC3S1500E-FG676. Tambahan pula, peranti FPGA ini berkemampuan untuk deprogram berulang kali menggunakan rekabentuk yang berlainan. Dalam kajian ini, keputusan simulasi bagi setiap bahagian pengekod dan penyahkod menunjukkan 260 sehingga 592 bit data suara diperolehi dalam lingkungan masa 20 ms bersesuaian dengan piawaian GSM. Keputusan muat turun juga didapati sama dengan keputusan simulasi bagi setiap bahagian pengekod dan penyahkod. Setelah melalui proses muat turun, maka cipset-cipset system perhubungan telefon mudahalih GSM dapat dihasilkan. ______________________________________________________________________________________ Global System for Mobile Communication (GSM) is a digital cellular communication network that has been used by most of the countries around the world. GSM mobile phone is used since 1991, and uses variety of error detection and error correction techniques in communication system to improve the services’ quality. Thus, a research has been done on six parts of encoder and six parts of decoder in the GSM mobile phone communication system in order to produce chipsets using VHDL. The communication system is important for detecting errors, correcting and protecting speech data during transmission and receiving. Xilinx ISE 7.1i software in VHDL description is used as a tool in the research to enable each part of encoder and decoder to be modeled synthesized, simulated and implemented before downloaded on the FPGA device Spartan3 XC3S1500E-FG676. Furthermore, the FPGA device is capable to be programmed many times using different design. In this research, the simulation result for each part of encoder and decoder shows that 260 until 592 speech bits are gained in 20 ms based on the GSM standard. The download result is also similar to the simulation result for each part of encoder and decoder. After the download process, the chipsets of GSM mobile phone communication system are produced.
