La description

（1） Advanced technology: Modern communication technology innovative experiment system adopts development platform of “DSP+FPGA”, on which, it realizes (several communication systems, ) such systems as digital base band transmission system, digital frequency band transmission system, digital programmable control switching system, CDMA mobile communication system as well as analog modulation system, and etc. （2） Powerful function: use communication system to be series with communication principle’s eleven technologies, such as speech coding technology, base band transmission technology, multiplex technology, analog modulation and demodulation technology, digital modulation and demodulation technology, synchronization technology, error-correcting code technology, interface technology, spread spectrum technology, duplex technology and exchange technology and etc. （3） Advanced structural design: adopt embedded modularization design. All modules are uniform size, flexible structure, and convenient upgrade. Users could block-building choose the needed modules according to their own requirements. （4） Abundant secondary development experiments: It could not only complete a large quantity of experiments for unit and system, but also experiments for secondary development and courses design, which could be the platforms of course design, graduation design, electronic design competition. The experiment system has four specialized secondary development module: single-chip computer secondary development module (C***1F series single-chip computer), CPLD secondary development module (MAX***0A series CPLD), DSP secondary development module (TMS*4XX series DSP), ARM secondary development module (LPC***0 series ARM7), which could offer *1 secondary development experiments all together. （5） Combination of hardware and software reflects the development tendency of experiment teaching: students emulate and calculate data or waveforms by software, such as QuartusII, Keil, CCS, ADS1.2 and etc, then physical verify, finally develop with their own hands, which reflects experiment teaching’s development tendency. （6） Sole innovative experiment module: GPRS module (self-equipped GSM network and SIM card ) and wireless transceiver could open experiments contents with design, application, research, which could enlighten students’ innovative thinking, but also broaden their horizons, and improve their comprehensive design ability. （7） Adopt plexiglass baffle for protection
