Dual-hop Transmissions with Fixed Gain Relays over Composite Fading Channels using Mixture Gamma Distribution
The end-to-end performance of dual-hop wireless communication system with fixed gain relays is investigated over independent non-identical composite Nakagamilognormal fading channels using mixture gamma distribution. Novel closed-form expressions for the outage probability, the average symbol error rate and the nth moments of end-to-end signal to noise ratio (SNR) for the considered system are ...
متن کاملPilot Assisted Wireless Transmissions†
The design of pilot assisted wireless transmissions is considered from signal processing and information theoretical perspectives. A general pilot placement model is presented and related figures of merit discussed. A survey of recent pilot assisted transmission theory and techniques is provided.
متن کاملAutomation of Manual Transmissions
The gears are changed automatically with the automated shift transmission. In contrast to the automatic step transmission, the ASG must interrupt the tractive force when shifting. This is more clearly detectable the higher the tractive force that is interrupted. For this reason, it can be surmised that ASG will be accepted mainly in small cars. The increasing use of electronic throttle simplifi...
متن کاملQuantum Anonymous Transmissions
We consider the problem of hiding sender and receiver of classical and quantum bits (qubits), even if all physical transmissions can be monitored. We present a quantum protocol for sending and receiving classical bits anonymously, which is completely traceless: it successfully prevents later reconstruction of the sender. We show that this is not possible classically. It appears that entangled q...
متن کاملFeasible Schedules for Rotating Transmissions
Motivated by a scheduling problem that arises in the study of optical networks we prove the following result, which is a variation of a conjecture of Haxell, Wilfong and Winkler. Let k, n be two integers, let wsj , 1 ≤ s ≤ n, 1 ≤ j ≤ k be non-negative reals satisfying ∑k j=1 wsj < 1/n for every 1 ≤ s ≤ n and let dsj be arbitrary non-negative reals. Then there are real numbers x1, x2, . . . , xn...
