signed tree

The frame of symbolic tree and calculation method of shannon entropy are presented depending on the binary partition,meanwhile the infection to the statistics parameters such as shannon entropy and so on,resulted by time delay,symbolic aggregate volum.

给出了二进制划分下符号树结构及其Shannon熵计算方法,讨论了时延τ、符号集大小NS和树层数(符号序列长度)对Shannon熵等统计量的影响。
