This article combines FBLMS algorithm with the blind decision algorithm, and proposes a frequency domain equalization algorithm which can be applied in the ATSC 8VSB system. In addition, with the shortcoming of the poor tracking capability of traditional frequency domain equalization algorithm in dynamic channel, this paper proposes a new equalizer tap update method which can effectively improve the...
The attribute reduction based on information entropy is different to that based on positive region in inconsistent information system. The problem of discernibility matrix in algebra view is analyzed, and an new discernibility matrix based on information entropy is proposed in this paper. This algorithm considers whether the objects compared are consistent, analyses in detail the degree of inconsistency...

High dimension and hard describing of cluster are the primary problems of clustering algorithm based on vector model. The conditional probability combined with rough set is introduced in this paper, and a information retrieval model based on fuzzy rough set is proposed, finally its document clustering algorithm is designed in detail. Especially the description and updating of cluster is studied in...
Underwater Acoustic Sensor Networks (UASNs) is an important and ideal information-gathering paradigm for aqueous environments. However the harsh acoustic traffic condition makes the task of efficient transmission difficult. This paper presents the bit error rate guided time limited energy optimal algorithm (TLEO) for UASNs, which resides between the network layer and the MAC layer. The main feather...
