Modulation Toolkit Example Programs
The National Instruments NI Modulation Toolkit For LabVIEW extends the built-in analysis capability ofLabVIEW with functions and tools for signal generation, analysis, visualization, and processing of standard and custom modulation formats. With this toolkit, you can rapidly develop custom applications for research, design, characterization, validation, and test of communications systems and components that modulate or demodulate signals. Applications for the Modulation Toolkit are numerous; it includes the modulation formats - AM, FM, PM, ASK, FSK, MSK, GMSK, PSK, QPSK, PAM, QAM - that are the foundation of numerous emerging wireless technologies such as 802.11 a/b/g, ZigBee (802.15.4), WiMax (802.16a), RFID, satellite communications, and commercial broadcast among others.
