GMSK
高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)

DDS
基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和
VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要
求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种
方法都能有效地实现DDS中波形存储表的设计。
(DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

SPI
design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip’s SPI MCP3202 12-Bit A/D converter. The 8 most significant bits of the converted data will be displayed on two seven segments of the NIOS development board. The sampling frequency is 20kHZ. Use a potentiometer.(design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip' s SPI MCP3202 12-Bit A/D converter.
