Two-relay distributed switch and stay combining
We study a distributed version of switch-and-stay combining (DSSC) for systems that utilize two relays. In particular, four different scenarios are considered, depending on a) whet...

Diversity-Multiplexing Tradeoffs in MIMO Relay Channels
—A multi-hop relay channel with multiple antenna terminals in a quasi-static slow fading environment is considered. For both full-duplex and half-duplex relays the fundamental di...

Level Crossing Rates of MIMO-MRC Ricean Channels and Their Implications on Adaptive Systems
- The second-order statistics of the time varying signal to noise ratio at the output of a multiple-input-multiple-output (MIMO) system with maximal ratio combining (MRC) are analy...

Accurate BER Analysis of QPSK Modulated Asynchronous DS-CDMA Systems Communicating over Rayleigh Channels
Abstract— The accurate average BER calculation of an asynchronous DS-CDMA system using random spreading sequences is studied in Rayleigh fading channels. An accurate closedform e...

Asymptotic statistics of mutual information for doubly correlated MIMO channels
In this paper, we derive the asymptotic statistics of mutual information for multiple-input multiple-output (MIMO) Rayleigh-fading channels in the presence of spatial fading correl...
