BPSK Transmitter Design Using FPGA With DAC and Pulse Shaping Filter to Minimize Inter-Symbol Interference(ISI)
In contrast to the sophisticated implementation of Binary Phase Shift Keying (BPSK) transmitter using Application Specific Integrated Circuit (ASIC), mixer, and Local Oscillator(LO) for carrier signal; Software Defined Radio (SDR) provides a high performance, efficient and re-configurable platform to integrate all these individual functions of BPSK transmitter. This paper presents a tutorial exploitation to design and implement BPSK transmitter using Field Programmable Gate Array (FPGA) for digital signal processing. The DSP-based BPSK transmitter is developed and compiled to VHDL (VHSIC Hardware Description Language) netlist. For proper interfacing D/A Converter (DAC) with FPGA, a HDL module of configurations of LTC-2624 Analog Module and clock synthesizer is integrated with the HDL netlist of BPSK transmitter.
