rs_decoder_31_19_6.tar
- Hard-decision decoding scheme Codeword length (n) : 31 symbols. Message length (k) : 19 symbols. Error correction capability (t) : 6 symbols One symbol represents 5 bit. Uses GF(2^5) with primitive polynomial p(x) = X^5 X^2 + 1
checkNodee_Behavioral_VHDL
- LDPC码校验节点（checknode）进行奇偶校验方程时的vhdl编程，硬件语言实现-LDPC check nodes (checknode) carried out at the time of parity equation VHDL programming, hardware language
polynom
- The polynomial solutions of the Hermite differential equation, with n a non-negative integer, are usually normed so that the highest degree term is 2z and called the Hermite polynomials H z. The Hermite polynomials may be defined explicitly by
nonsythasizable8pointfft
- A Fast Fourier Transform(FFT) is an efficient algorithm for calculating the discrete Fourier transform of a set of data. A DFT basically decomposes a set of data in time domain into different frequency components. DFT is defined by the following equa
moveophone
- 移动式的游戏控制器基于vhdl. 简单结构 目前只能识别led-Due to the recent trend in creating devices that allow the playing of games using movement rather than a traditional joystick, controller, or keyboard, we felt that a project that followed this idea would be interestin

- 使用fpga实现任意长度，任意方程的伪随机系统码-Using FPGA to achieve arbitrary length, any equation of the pseudo random system code
tlc549adc
- 利用状态机实现对TLC549的采样控制，实验时可调节电位器RW1（在开发板底板左下角），改变ADC 的模拟量输入值，数据采集读取后在数码管上显示。可以自己用万用表测一下输入电压， 然后与读取到的数据比较一下。注意：数码管显示的数据不是最终结果，还需要转换。 转换方法： 比如，采样电压值为V ，ADC转换后读取的8位二进制数为D，Vref为参考电压值，这里是2.5V 那么以下等式成立： V=（D/256）*Vref-Using the state machine to ac
