Abstract

In a multi input multi output (MIMO) system bit rate is increased due to multiple antennas but at the same time energy consumed also increases. In this paper, optimum solutions to that problem are addressed and their comparison is done in terms of total energy consumed and their processing times. The technique employed in those algorithms is using adaptive bit allocation to OFDM subcarriers in a frequency selective fast fading channels. To perform adaptive Modulation in OFDM systems requires Channel Estimation in prior to Adaptive modulation.
