Tenders Description & Specification for CDMA DSSS Trainer

CDMA DSSS Trainer

Trainer provides a basic understanding of the concepts behind CDMA, and various issues that need to be considered in the design of a DSSS system.These include generation of various pseudorandom (PN) codes like Gold, MLS & Barker with programmable tappings, variable chip rate, and digital modulations BPSK, QPSK & digital AWGN noise with programmable FIR low pass filter. Bit error rate (BER) measurement with known data sequence, overall data rate dependency parameters, spreading & dispreading with DSSS, SNR control, offset control & so on can be performed on model.

Technical Specifications
