摘要
本文旨在为胶囊内窥镜系统提出一种提高图像传输速率并降低误码率的方法--MIMO(Multiple Input Multiple Output)技术来提高传输可靠性。为了不增加发射端的体积和功耗,我们使用单个发送天线,而在接收端采用多个接收天线即SIMO(Single Input Multiple Output)系统,同时我们仿真了各种分集接收技术的性能,选出一种最优的接收合并方式。
To solve the poor quality image transmission, this paper proposes a method to improve the transfer rate and reduce error rate of the image by using-MIMO (Multiple Input Multiple Output) technology for capsule endoscopy. In order not to increase the size and power consumption of the transmitting end, we use a single transmission antenna, while at the receiving end, we use multiple receiving antennas, that’s SIMO (Single Input Multiple Output). In the experiments, we simulated the performance of receive diversity techniques, and selected an optimal method of diversity combination.
