Product Specification

advanced communication trainer : lab equipment

Product Description

(1) The experiment apparatus has designed a complete direct-spread code-division multiple access (DS-CDMA) mobile communication system, which realizes wireless transceiver by carrier and tightly combines textbook of Spread Spectrum Communication, and outlines the key points of textbook, such as GOLD sequence, spread spectrum and despread spectrum, acquisition and tracking, synchronization extraction, error correction encoding and so on, enabling users to further understand the essence of CDMA by experiments.  

(2) CDMA system includes many functions, such as direct spread spectrum and despread spectrum, code division multiple access, acquisition and tracking of pseudo-random sequence, bit synchronization, frame synchronization extraction, carrier recovery, error correction coding and encoding, which could compose a complete CDMA mobile communication system. Simultaneously, it could establish big CDMA system between two or multiple experiment apparatuss through wireless transmission. 

(3) Adopt plexiglass baffle for protection 


II. Performance Parameters 

(1) AC, DC power supply 

Input: AC 220V±10%

Output: DC ±12V/±5%, ±5V/±5%, -8V/±5%

(2) CDMA Transmitter Receiver
