We are a prominent Exporter and Supplier of Mobile Communication Trainer Kit. VPL-2131L provides a basic understanding of the concepts of CDMA and various issues of a DSSS system. These include the usage of pseudorandom (PN) codes and digital modulations BPSK. It has digital modulation & demodulation along with direct sequence spread spectrum (DSSS) generation and decoding, data signals, zero random bit signal generation.
