中文说明：部分实现了追踪测速迭代松弛算法，使用拉亚普诺夫指数的公式，可以得到很精确的幅值、频率、相位估计，调试通过可以使用，LDPC码的完整的编译码，包括调制，解调，信噪比计算。
English Description：
Part of the implementation of the tracking velocimetry iterative relaxation algorithm. La Jaap Andrianof index of the formula can be very precise amplitude, frequency and phase estimation is obtained, through the debugger can be used, the encoding and decoding of LDPC codes, including modulation, demodulation, signal to noise ratio is calculated.
