Understanding CDMA-DSSS Communication System with BER Measurement Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12519

Indian Lab Suppliers supplies the CDMA-DSSS Communication System with BER Measurement Training System (Product ID: 12519), part of the Communication Equipment range under Laboratory equipment, an instrument-grade platform for studying CDMA using Direct Sequence Spread Spectrum (DSSS), with separate modulator and demodulator sections, Bit Error Rate (BER) measurement and built-in AWGN and Doppler impairment generators.

Note on scope: this is a more advanced, instrument-grade DSSS platform than our basic CDMA-DSSS/FHSS Trainer (Product ID 12496), adding BER measurement, a built-in AWGN noise generator, a frequency-offset (Doppler) generator, and BNC-based I-Q signal analysis. See also our CDMA - DSSS Trainer (Product ID 12555), a closely related hardware-board DSSS platform with a similar code/modulation/impairment feature set. Please confirm with our team which platform best fits your curriculum requirement.

Quick Answer

This training system provides a complete CDMA-DSSS modulator and demodulator with separate sections for higher learning, letting students generate Gold, Maximum Length Sequence (MLS) and Barker spreading codes with user-selectable tappings, study baseband BPSK/QPSK/OQPSK modulation with a Root Raised Cosine spectral shaping filter, introduce AWGN noise and Doppler frequency offset as channel impairments, and measure Bit Error Rate against signal-to-noise ratio, all with real-time software analysis in the digital time, analog time and frequency domains.
