The present invention provides a system (300-400), apparatus (300-400), and method for an energy-based antenna selection technique in which the antenna that observes the largest SNR averaged over all carriers per sub-band (405) is selected for space-time coded MB-OFDM systems. Due to the frequency-selective nature of the system, different sub-band may have different channel gaining effect from the multi-path channels. We can perform energy-based antenna selection per sub-band, and the simulation results show that the proposed technique works not only for MB-OFDM UWB channels with shadowing, but also for the same channel without shadowing. |
