Consider a random access communication scenario over channel whose operation is defined for any number of possible transmitters. As in the model recently introduced by Polyanskiy Multiple Access Channel (MAC) with fixed, known transmitters, assumed to be invariant permutations on its inputs, and all active transmitters employ identical encoders. Unlike model, proposed scenario, neither nor rece...

Radar systems, based on bistatic radar concept attracted a substantial attention in the recent years. Passive coherent location systems using “transmitters of opportunity” like radio or TV broadcasters, GSM base stations, satellite communication and GNSS signals proved their potential in detection and tracking moving targets over a significant area. In this paper the multistatic location system...

High-speed, single-frequency transmitters at 980 nm are reported, with open eye diagrams up to 40 Gbit=s and error-free operation up to 35 Gbit=s. The transmitters consist of a short-cavity, distributed Bragg reflector (DBR) laser with an integrated electro absorption modulator fabricated using a quantum well intermixing processing platform. This represents the fastest bit-rate operation to dat...

In order to avoid interference in cellular telephone networks, sets of radio frequencies are to be assigned to transmitters such that adjacent transmitters are allotted disjoint sets of frequencies. Often these transmitters are laid out like vertices of a triangular lattice in a plane. This problem corresponds to the problem of multicoloring an induced subgraph of a triangular lattice with inte...
