LDPCBSN
LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)
(LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

测距仪测距的过程中，由于受到仪器本身的系统误差以及外界环境影响，会造成测距精度的下降。为了提高测距的精度，我们需要对测距的结果进行改正，可以分为三种类型的改正：仪器常数的改正、气象改正和倾斜改正。(Rangefinder ranging process, due to systematic errors in the instrument itself and the external influences, ranging accuracy will result in a decline. In order to improve ranging accuracy, we need to correct the results of the distance, can be divided into three types of corrections: the correction instrument constant, meteorological correction and inclination correction.)
