8064 同时受计算机计算字长的限制,算法会有一定的舍入误差,误差的积累有时会导致协方差矩阵失去非负定性和对称性,从而使得滤波计算发散。 Restricted by the computer word long at the same time, the algorithm will have certain rounding error, error sometimes leads to the accumulation of covariance matrix loss of nonnegative qualitative and symmetry, so as to make the filtering divergence.
8065 因而进一步提出了C-SVSF的平方根形式,即平方根容积平滑变结构滤波算法。 Further put forward the C - the square root of SVSF form, namely square root volume smooth variable structure filter algorithm.
8066 最后在动力定位船状态估计仿真实验中,说明了算法的有效性。 Finally in the ship dynamic positioning state estimation simulation experiments, illustrates the effectiveness of the algorithm.
8067 提出一种基于存储(memory-based,MB)机制的Luby变换码的编译码方法,来实现信息在二进制删除信道(binary erasure channel,BEC)中的可靠传输。 Based on a storage (memory - -based, MB) mechanism Luby transform code decoding method, to implement the information deleted in binary channel (binary erasure channel, BEC) of reliable transmission.
8068 首先,发送端的编码器采用泊松鲁棒孤子分布(Poisson-robust soliton distribution,PRSD)产生普通编码包,同时产生携带存储信息的"存储包"。 First, send the encoder using robust soliton Poisson distribution (Poisson - robust soliton distribution, PRSD) produce ordinary code package, at the same time produce carry information stored "storage bag".
8069 然后,源源不断在BEC中发送编码包和"存储包"给接收端。 Then, flowing in BEC send code packages and "storage bag" to the receiver.
8070 接收端的译码器根据接收到的"存储包"的数量不同,采取不同方式对输入包进行译码。 Decoder based on the received at the receiving end "storage package" is different, the number of different ways to decode input package.
8071 如果"存储包"全部被接收,则所有输入包都能通过"存储包"中的存储信息直接获得; If the "storage package" are all receiving all input packets can be through direct access to information stored in the "storage package" of;
8072 如果部分"存储包"丢失,则结合"存储包"和置信传播(belief propagation,BP)算法进行译码; If you lose part of the "storage package", combining "storage package" and belief propagation (are propagation, BP) decoding algorithm;
8073 如果所有"存储包"丢失,则仅采用BP算法进行译码。 If you lose all the "storage package", you only using BP algorithm to decode.
