8 permanent sample plots in the Polar-Birch (Populus davidiana Dode- Betula platyphylla Suk) Secondary Forests and 4 permanent observation plots in the Spruce-Fir forests in over-cutting forest in Changbai Mountain, Northeast China, were established. We used the diameter data of Aspen-Birech forest to model the Weibull diameter distribution. At the same time, the main coniferous species, which is...
A study on the construction method of the orthogonal complementary sets group used for CDMA coding in the sequence analysis, meanwhile, we make the analysis of the relation between complementary Set and the orthogonal complementary Sets group. Furthermore, we design the method which can be used to constitute the orthogonal complementary sets group by the known complementary set, put forward the necessary...
