The present invention is related to a statistical multiplexing method and apparatus using a multi-dimensional orthogonal resource hopping multiplexing method in a wired / wireless communication systems where a plurality of communication channels, which are synchronized through a single medium, coexist. The present invention, in order to implement a generalized statistical multiplexing communication system using a multi-dimensional orthogonal resource hopping multiplexing method, comprises a multi-dimensional hopping pattern generator which is located in the primary communication station, a data symbol modulator that modulates data symbols based on the corresponding orthogonal resource hopping pattern generated by said multi-dimensional hopping pattern generator, a collision detector and controller that detects whether a collision occurs or not between the multi-dimensional hopping patterns and compares the consistency of the data symbols toward the secondary communication stations between said collision interval, a transmission power controller that controls the transmission power of the remaining parts excluding the parts where the multi-dimensional hopping patterns collide and the transmission is stopped due to transmitting data symbol inconsistency and compensates for the loss in the average reception energy due to a transmission stoppage.

A method and apparatus that couple a change input scan chain test pattern with an initialization scan chain test pattern such that a resultant scan chain test pattern is produced, and apply the resultant scan chain test pattern to at least one combinational logic path. In one embodiment, the coupling is achieved by interleaving the change input scan chain test pattern with the initialization scan chain test pattern. In another embodiment, the coupling is achieved by creating a constructed test pattern set from the change input and the initialization scan chain test pattern.

Target subtree setting means sets a target subtree relating to a content portion. Occurrence mode detecting means collates a target subtree relating to a content with a tree relating to each of past structured / hierarchical contents and detects an occurrence mode of each node of the target subtree. Statistical information generating means generates statistical information concerning an occurrence frequency of the occurrence mode of each node in the target subtree. Classifying means classifies each node of the target subtree based on the statistical information and a result of detecting the occurrence mode. Matching pattern generating means generates the matching pattern for the target content portion based on the classification. The structured / hierarchical contents are identified by use of the matching pattern.
