On limits of wireless communications in a fading environment when using multiple antennas
- Wireless Personal Communications
, 1998
"... Abstract. This paper is motivated by the need for fundamental understanding of ultimate limits of bandwidth efficient delivery of higher bit-rates in digital wireless communications and to also begin to look into how these limits might be approached. We examine exploitation of multi-element array (M ..."

communication links. We explore the important case when the channel characteristic is not available at the transmitter but the receiver knows (tracks) the characteristic which is subject to Rayleigh fading. Fixing the overall transmitted power, we express the capacity offered by MEA technology and we see how
Capacity of a Mobile Multiple-Antenna Communication Link in Rayleigh Flat Fading
"... We analyze a mobile wireless link comprising M transmitter and N receiver antennas operating in a Rayleigh flat-fading environment. The propagation coefficients between every pair of transmitter and receiver antennas are statistically independent and unknown; they remain constant for a coherence int ..."

Adaptive Resource Allocation in Composite Fading Environments
- Global Telecommunications Conference, 2001. GLOBECOM '01. IEEE
"... We obtain optimal resource allocation policies for a single user single-carrier system and a multipleaccess multi-carrier-CDMA system when the transmitter adapts to the variations in the short-term mean (slow fade) in a combined slow and fast fading (composite fading) environment. For the single use ..."

Performance Comparison of AODV & DSR Routing Protocol in a Fading Environment
"... In most of the performance comparison of routing protocols, the effects of fadings are rarely considered. The protocols are instead compared in terms of traffic intensity, node intensity and mobility etc. In this paper, the performance of two classic routing protocols for adhoc network such as AODV ..."

& DSR are compared for Ricean and Rayleigh fading environment. Qualnet Simulator has been used for the simulation and performance analysis. It was found that DSR protocol gives more throughput and less average end-end delay in comparison to AODV for both Ricean & Rayleigh fading environment.
