CDMA - DSSS Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12555

Indian Lab Suppliers supplies the CDMA - DSSS Trainer (Product ID: 12555), part of the Communication Equipment range under Laboratory equipment, an advanced platform for Direct Sequence Spread Spectrum (DSSS) system design, covering multiple spreading-code families, BPSK/QPSK/OQPSK code modulation, channel impairment generation and bit-error-rate measurement.

Note on scope: this is our advanced DSSS platform with multiple spreading-code families, BPSK/QPSK/OQPSK modulation, AWGN and Doppler impairment generation, and BER measurement. For a simpler introduction to CDMA and DSSS concepts, see our Basic CDMA Trainer, and for a closely related instrument-grade platform with host-software BER analysis, see our Understanding CDMA-DSSS Communication System with BER Measurement (Product ID 12519). Note also our identically-styled CDMA - DSSS Trainer with BER Measurement (Product ID 12556), which focuses specifically on detailed BER-measurement instrumentation. Please confirm with our team which platform best fits your curriculum requirement.

Quick Answer

This trainer lets students study the design considerations of a DSSS system: generating Gold, maximal-length and Barker pseudo-random codes, applying BPSK/QPSK/OQPSK code modulation with raised-cosine spectral shaping, adding AWGN and Doppler channel impairments, and measuring bit error rate, spreading/despreading behaviour, SNR and offset control.

Key Features

Direct Sequence Spread-Spectrum (DSSS) modulator and demodulator · programmable chip rates up to 10 Mchip/s · spreading codes: Gold sequences, maximal-length sequences, and Barker codes (length 11 or 13) · code modulation: BPSK, QPSK or OQPSK with raised-cosine square-root output spectral shaping filter at 20%, 25% or 40% rolloff · internal generation of pseudo-random bit stream and unmodulated carrier for test purposes · built-in channel impairments: Additive White Gaussian Noise (AWGN) and frequency offset (Doppler) · sequential code search with 4-bit soft-quantized demodulated bits · extensive monitoring of receiver lock and carrier frequency error.

Why Buy from Indian Lab Suppliers

Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this CDMA - DSSS Trainer alongside its broader Communication Equipment catalog, with documentation such as a Certificate of Origin available on request for institutional and export orders.

Frequently Asked Questions

How does this differ from your Basic CDMA Trainer?
This platform offers multiple spreading-code families (Gold, maximal-length, Barker), BPSK/QPSK/OQPSK modulation, AWGN and Doppler impairments, and BER measurement, while our Basic CDMA Trainer introduces core CDMA concepts with a fixed 15-bit PN sequence and BPSK/PWM modulation. Please confirm with our team which platform best fits your curriculum requirement.

Can bit error rate be measured on this trainer?
Yes, BER can be measured with a known data sequence, alongside SNR control and offset control.

Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
