JSI的音标

And evenness indexes Jsi range from 0.670 to 0.956. On the base of similarity coefficients CC in Table 3, the five different kinds of habitats can be clearly clustered into 2 groups by the systematic clustering: original forest group and secondary habitat group.

根据不同生境物种的相似性系数CC进行系统聚类，5种生境在相似性系数为0.226水平时已被归并为两组，即原生森林组和次生环境组。

In this chapter, an algorithm of iterative estimating jamming state information is proposed specially for OFDM systems based on linear modulation so as to gradually improve the correct rate of estimating JSI with the iterative estimation and then improve the performance of the whole system.

本章还专门针对基于线性调制的OFDM系统提出了一种迭代估计干扰状态信息的算法。通过迭代估计干扰状态信息，其准确性逐渐提高，从而也提高了整个系统的抗干扰性能。

If exact JSI was not available, however, an iteratively joint jammer state estimation and decoding algorithm was proposed.

同时，在无法得到精确干扰状态信息的情况下，提出了一种迭代干扰状态估计及译码算法。
