碰撞在射频识别系统中是一个非常常见的问题，如何有效解决这个问题对整个系统来说是很重要的。射频识别

系统是由两个部分组成的：一个是标签；另一个是读写器。在读写器的作用范围内有多个标签同时应答，这时就会产生碰

撞。提出了一种改进的二进制搜索算法，使用这种算法能够在更短的时间内比二进制搜索算法、纯ALOHA和时隙ALO．

HA 法识别更多的标签。-Collision in the radio frequency identification systems is a very common problem, how to effectively solve this problem the whole system is very important. Radio frequency identification system is composed of two parts: a label　the other is the reader. The role of the reader there are multiple tags at the same time within the response, then it will produce collisions. An improved binary search algorithm, using this algorithm can be in a much shorter period of time than the binary search algorithm, pure ALOHA, and slot ALO. HA the Identification of additional labels.
