To improve the data transmission rate and use spectrum flexibly, a new spectrum allocation method for Multiband Impulse Radio UWB (MB-IR-UWB) is proposed in thi
An all-optical cryptographic device for secure communication, based on the properties of soliton beams, is presented. It can encode a given bit stream of optica
This paper investigates the outage performance of a cognitive relay network considering best relay selection in Nakagami-m fading environment. The secondary use
