| Popis: | This paper give the brief description of digital communication system.Digital communication is more reliable, secure and efficient than that of analog communication.In Digital communication,BPSK is most important and efficient technique in terms of signal power. In this paper BPSK modulator and demodulator are purely design by using hardware description language (VHDL) and implementing it on Spartan 3E FPGA kit. I. Introduction In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. A digital communication system is more reliable than an analog. The aim of the paper is to create a BPSK (Binary Phase Shift Keying) modulator and demodulator using Xilinx ISE 12.3 software. BPSK consist of modulator a channel and demodulator. The modulated signal was achieved in the first Spartan 3E board, passed through a channel and transmitted to the second board, which behaves as a demodulator. |
