Abstract : Here we propose an Antenna selection schemes using MIMO-OFDM wireless systems. In the MIMO OFDM
systems, the expressions are evolved for both the energy efficiency and the energy efficiency- spectral efficiency (EE-SE)
trade-off. The attained result from these systems tells that the system has significant loss in the energy efficiency. Here a
method is proposed for better performance of energy-efficiency that is adaptive selection method. The proposed system
mainly depends up on the condition of channel when we chose the number of active RF (radio frequency) chains and the
antenna indices. This scheme is improved by using the small number of antennas from extensive search technique. Further,
we impose an algorithm for acquire a near-optimal performance with lower complexity compared with (optimal) exhaustive
search method.In this paper we describe about the adaptive modulated multi-input multi-output orthogonal frequency
division multiplexing which enables the effective communications in Ultra Wide Band (UWB) systems with low signal-to
noise ratio. An adaptive resource allocation algorithm based on sequential allocation is proposed from the adaptive power
research and bits allocation scheme in modulated MIMO-OFDM for UWB communication system. The simulation results
suggest that the scheme is much simpler and more practical than the optimal allocation scheme at the small expense of
performance.
