針對(duì)傳統(tǒng)集成電路(ASIC)功能固定、升級(jí)困難等缺點(diǎn),利用FPGA實(shí)現(xiàn)了擴(kuò)頻通信芯片STEL-2000A的核心功能。使用ISE提供的DDS IP核實(shí)現(xiàn)NCO模塊,在下變頻模塊調(diào)用了硬核乘法器并引入CIC濾波器進(jìn)行低通濾波,給出了DQPSK解調(diào)的原理和實(shí)現(xiàn)方法,推導(dǎo)出一種簡(jiǎn)便的引入?仔/4固定相移的實(shí)現(xiàn)方法。采用模塊化的設(shè)計(jì)方法使用VHDL語(yǔ)言編寫出源程序,在Virtex-II Pro 開發(fā)板上成功實(shí)現(xiàn)了整個(gè)系統(tǒng)。測(cè)試結(jié)果表明該系統(tǒng)正確實(shí)現(xiàn)了STEL-2000A的核心功能。 Abstract: To overcome drawbacks of ASIC such as fixed functionality and upgrade difficulty, FPGA was used to realize the core functions of STEL-2000A. This paper used the DDS IP core provided by ISE to realize the NCO module, called hard core multiplier and implemented CIC filter in the down converter, described the principle and implementation detail of the demodulation of DQPSK, and derived a simple method to introduce a fixed phase shift of ?仔/4. The VHDL source code was designed by modularity method , and the complete system was successfully implemented on Virtex-II Pro development board. Test results indicate that this system successfully realize the core function of the STEL-2000A.

The ICA/BSS algorithms are pure mathematical formulas, powerful, but rather mechanical procedures: There is not very much left for the user to do after the machinery has been optimally implemented. The successful and efficient use of the ICALAB strongly depends on a priori knowledge, common sense and appropriate use of the preprocessing and postprocessing tools. In other words, it is preprocessing of data and postprocessing of models where expertise is truly ne
