LDPC研究者MacKay提供的校验矩阵H和对应的G，其中H的行重12，列重6，行数504，列数1008，任意两行不含围长为4的圈(LDPC researchers MacKay, the calibration matrix corresponding to the H and G, in which the re-H 12, series 6, a few 504, cited 1008, the two firms were non-arbitrary girth to the ring 4)

matlab中ctrllab工具箱，对系统稳定判断有用(in ctrllab matlab toolbox, useful to determine the stability of the system)

This is a code that allow crop an face image proportionally, two point (eyes) and obtains the result.

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)
