Abstract: | Future high speed mobile applications require diverse Quality of Service (QoS). To provide flexible data rate services while
satisfying the low delay requirements, adaptive MIMO OFDM is a promising technique over time varying channels. In this paper
a variable power adaptive MIMO OFDM system under imperfect CSI using cross layer design for mobile ad hoc networks is proposed.
Data throughput is maximized while maintaining the delay QoS requirements in the presence of channel estimation errors. Numerical
results show that the variable power adaptive MIMO OFDM system provides better spectral efficiency than its constant power
counterpart. |
