This paper presents an analysis on the performance of decode- and-forward cooperation transmissions in Rician fading channels. The users send the signals using multiband DS-CDMA transmission; the particular complete complementary code sets are used as spreading sets and to provide orthogonality and signal separation. These codes sets have an impulsive autocorrelation sum among each set and orthogonality...
This paper studies the probability of packets being successfully delivered to their intended receivers (vehicles) on a highway by taking multi-user interference, path loss, and fading into account. This probability affects the efficiency of V2V communications for safety purposes in vehicular networks. The presented mathematical framework can be employed in designing the safety applications of VANETs...
We consider the problem of several users transmitting packets to a base station, and study an optimal scheduling formulation involving three communication layers, namely, the medium access control, link, and physical layers. We assume Markov models for the packet arrival processes and the channel gain processes. Perfect channel state information is assumed to be available at the transmitter and the...
