Abstract :This paper presents the simulation results of binary frequency shift keying insert ignore into journalissuearticles values(BFSK); and binary phase shift keying insert ignore into journalissuearticles values(BPSK); modulation techniques in FPGA complier. Both modulation techniques are proposed in low power consumption systems. In addition, these modulation techniques are used high speed systems. Also, in this paper BPSK and BFSK modulations are compared to bit error rate insert ignore into journalissuearticles values(BER);. BPSK modulation technique has BER low than BFSK modulation in AWGN channel. Thereby, as satellite communication for systems which need very high speed data transfer, BPSK modulation technique is preferred. For BPSK and BFSK modulation techniques, modulators were designed using FPGA complier insert ignore into journalissuearticles values(Quartus II 9.1);. In Quartus II complier, results of simulation are observed using vector waveform file.
