摘要
远程医疗是今后医学发展的一个重要方向。通过对正交拉丁方特性的讨论,推演出其中存在的一种可利用的对消机制,提出了一种基于此对消机制的远程医疗系统中传输数据的调制解调方法,能够更好地解决多个用户共用一个信道时互相干扰的问题。同时,在单信道用户数的扩展及通信信道利用率的提高方面也有潜在的优势。
Telemedicine is the significant object of the medicine in the future. This paper introduces an available counteractive mechanism which is derived from the orthogonal Latin squares, and a modulation method for the data transmission of the telemedicine system is proposed. This method could resolve the problem of overlapping interference from multiple accesses on one channel efficiently. At the same time, it also has potential advantages in increasing the user numbers in one channel and improving the channel utilization.
