Guest editorial: optical wireless communications

the last two decades, wireless communications has gained enormous popularity, offering attractive options for many personal and organizational communication needs due to major intrinsic characteristics such as flexibility, cost effectiveness, and mobility. Two transmission techniques for wireless communications have been deployed so far; Radio Frequency (RF) and Optical Communications. While th...

role in information technology, Internet, multimedia communications, forensics, security systems, and handheld applications. Wireless and optical communications have received tremendous interests from both academics and industries over recent years which led to a significant growth of research and development activities in the fields. There are still lots of challenges in the design of an effec...

Guest Editorial Energy-Efficiency in Optical Networks

THE increasing concern for environmental and cost issues has made energy efficiency in telecom networks an important theme. According to a recent report [1], today’s networks are wasting a lot of energy by consuming 10,000 times more energy than what is really needed. The Internet currently consumes about 0.4% of the total electricity in broadband-enabled countries and is foreseen to quickly re...

Guest Editorial Compressive Sensing for Biomedical Imaging

W HILE it is common knowledge that most images can be greatly compressed, compressive sensing (CS) theory has established that such compression can be done during the data acquisition process and then the uncompressed image can be recovered through a computationally tractable optimization procedure such as L1-norm minimization [1]–[4], or greedy algorithms [5]. In the field of biomedical imagin...
