Abstract
Binary Phase Shift Keying represents the simulation results of binary digital modulation schemes. Here for BASK and BPSK modulation techniques use FPGA algorithm. If multiplier block is used for multiplication bit stream with carrier signal, used time will rises. In addition using multiplier block obtained simulation results were analyzed and compared to other simulation results. Source consumptions of FPGA-based BASK modulation technique and BPSK modulation technique were compared. Also, for different modulation algorithm, source consumptions of BASK and BPSK modulation technique were analyzed using VHDL. Designed modulators using VHSIC (Very High Speed Integrated Circuit) Hardware Description Language (VHDL) was realized on high speed FPGA (Field Program Programmable Gate Array). Because for used modulation technique data rate transfer is fairly important in wireless communication systems. The highest speed data rate transfer can be realized using fiber optic cables. In addition, BER (Bit Error Rate) of BASK and BPSK modulator was compared using MATLAB simulation program. Binary data rate is same for BPSK and BASK. BPSK and BASK modulations were designed on FPGA using VHDL hardware description language.
Highlights
Data modulators, especially those intended to produce constant envelope output signals, are ―high-leverage‖ components in that even very small deviations from ideal in their behavior can lead to large degradations in overall system performance
BPSK and BASK modulation techniques based on FPGA
It is illustrated that Bit Error Rate (BER) of BASK high than BER of BPSK
Summary
Especially those intended to produce constant envelope output signals, are ―high-leverage‖ components in that even very small deviations from ideal in their behavior can lead to large degradations in overall system performance. The ASK modulation/demodulation scheme, for both RF-band and baseband transceiver, was presented This design is realized on future mobile memory I/O interface for energy efficient [5]. BPSK is as well as showing better Bit Error Rate (BER) compared to BASK. Bit error rate of BPSK modulation techniques was compared using MATLAB. 1. The aim is to generate BPSK modulation which is a popular modulation technique used in communication industry, its symbol error performance and bandwidth efficiency. 1.The aim of the paper is to generate BPSK modulation which is a popular modulation technique used in communication industry, its symbol error performance and bandwidth efficiency If ―1‖ was transmitted, the modulated signal remained the same as the carrier, with 0o initial phase, but if ―0‖ was transmitted, the modulated signal would change with 180o, like shown in fig. 1.The aim of the paper is to generate BPSK modulation which is a popular modulation technique used in communication industry, its symbol error performance and bandwidth efficiency
