In this paper, a more accurate outage performance analysis is obtained by employing order statistics for multiple-input multiple-out two-way relay system with joint transmit/receive zero- forcing. Furthermore, closed-form upper and lower bounds are first derived for the overall outage probability when there exist spatial correlations at the relay. Analysis and simulation results indicate that the...
This paper addresses the optimization of wireless sensor networks for distributed detection applications. In general, the jointly optimum solution for the local sensor decision rules and the fusion rule is very difficult to obtain and does not scale well with the number of sensors. In this paper, the joint optimization of the local sensor decision rules and the fusion rule is facilitated by using...
In this paper, we consider a wireless communication scenario in which the channel output is marginally Gaussian, but not jointly Gaussian. In particular, we study the joint probability distribution of channel outputs in correlated Rayleigh fading channels in response to constant power signaling, such as M-ary phase shift keying (MPSK). We show that the distribution of the channel output at any given...
In this paper, we consider an incremental relaying protocol based on an amplify-and-forward transmission in conjunction with a best relay selection scheme over non-identically distributed relay channels. In order to satisfy the spectral efficiency and the bit error rate (BER) requirements, adaptive modulation is applied to our proposed scheme. We derive the average spectral efficiency, average BER...
