Atmospheric turbulence can cause a significant performance degradation in free space optical communication systems. An efficient solution could be to exploit the temporal diversity to improve the performance of the transmission link. Depending on the tolerable delay latency, we can benefit from some degree of time diversity that we can exploit by employing(More)
—Wireless Capsule Endoscopy (WCE) generates a large number of images in one examination of a patient. It is very laborious and time-consuming to detect the WCE video, and so limits the wider application of WCE. Color similarity measurement is the key technique of color image segmentation and recognition, as well as the premise of bleeding detection in WCE(More)
Depending on the tolerable delay latency, we can benefit from some degree of time diversity in free-space optical links, by employing channel coding and interleaving. We present a comparative study of the performance of different channel coding techniques at the presence of time diversity. We show that turbo-codes are particularly efficient under strong(More)
Communication between large numbers of I/O ports will require switching of Terabit aggregate bandwidth to meet the needs of future applications. Advances in fiber amplifiers have increased interest in transparent optical networks which do not rely on data regeneration in the electronic domain. Additionally, since polarization compensation in a single mode(More)
