The self-seeded cavity appeared in the last few years as a colorless and low cost solution for wavelength division multiplexing (WDM) access. Although the self-seeded source presents a simple architecture, its behavior has been misunderstood for a long time. In this paper, we explain its operating principles and why we can define such a source […]

We consider a communication network, where two mutually interfering 2-user MIMO Multiple Access Channels (MAC) operate simultaneously via the same time-frequency space, and characterize the capacity region of this network when the channel matrices satisfy a strong interference condition. This interfering MAC (IMAC) with aforementioned channel matrices is called strongly ordered IMAC in this paper. To characterize the […]

The accidents between trains are increasing due to negligence of intelligent techniques implemented in the trains and improper control signaling from the Train Traffic Control Station (TTCS). The Train Tracking Chip (TTC) modules and Train Identification Chip (TIC) modules are using to sense the presence of trains on the same track. The signals from the […]
