CDMA Mobile Communication Trainer Kit (VPL-2131L)

VPL-2131L provides a basic understanding of the concepts behind CDMA, and various issues that need to be  considered in the design of a DSSS system. It has digital modulation & demodulation along with direct sequence spread spectrum (DSSS) generation and decoding, data signals, zero random bit signal generation.

FEATURES

• VLSI based design
• GOLD sequency, spread spectrum and de-spread spectrum
• Acquisition and tracking, synchronization extraction, error correction encoding.
• Direct spread spectrum and de-spread spectrum
• Code division multiple access.
• Acquisition and tracking of pseudo-random sequence, bit synchronization.
• Frame synchronization extraction, carrier recovery, error correction coding and encoding.
• Plexy-glass baffle for protection.
