迭代解码算法Weighted Bit-Flipping Algorithm，可对比数据计算误码率(Iterative decoding algorithm for Weighted Bit-Flipping Algorithm, error rate can be calculated comparing the data)

交织码通常表示为（M，N），分组长度L=MN，交织方式用M行N列的交织矩阵表示。一般，交织方式分为分组交织和卷积交织。分组交织的交织矩阵按列写入，按行读出；去交织矩阵按行写入按列读出。卷积交织的交织矩阵和去交织矩阵的写入与读出均按行进行。(Intertwined code is usually expressed as (M, N), the packet length L = MN, interwoven manner, said interwoven matrix with M rows and N columns. In general, interwoven into the packet interleaving and convolutional interleaving. Grouping of interwoven interwoven matrix column to write, to read de-interlacing matrix read out by column written by line by line. Convolutional interleaving interleaving matrix and de-interlacing matrix to write and read are OK.)

针对无线射频识别(radio frequency identification，RFID)系统的多标签碰撞问题，在分析RFID标签编码规则的基础上，提出根据标签编码规则进行标签分组和标签预淘汰的方法，在读写器识别的初始阶段根据特定的规则淘汰部分标签，从而减少系统工量，提高系统工作效率.实例证明：在不增加标签结构复杂度的基础上，充分利用已有的有效信息能够有效减少阅读器的查询次数和系统的总通信量．(For radio frequency identification (radio frequency identification, RFID) system is a multi-tag collision problem, based on the analysis of the RFID tag encoding rules based on the proposed label grouping and labeling pre-elimination method according to the label encoding rules identified in the initial reader phase-out of the label according to specific rules, thus reducing the amount of system engineering, to improve system efficiency examples demonstrate: the label without increasing the complexity of the structure on the basis of full and effective use of existing information can be effective in reducing the number of queries and reader total traffic of the system.)

We present in this paper a new method for blind source separation which is adapted to the case where the sources have different morphologies. We show that the morphology diversity concept leads to a new and very efficient method, even in the presence of noise.
