Abstract

The speedy dissemination of digital consumer electronics devices within personal area causes increments of multimedia communication and advent of entertainment networking. This feature of communication requires high data-rate transmission. In order to meet the demand, in this paper, we apply multiple antenna schemes to MB-OFDM UWB system. And to use the UWB system with multiple antennas for various channel environment, some adaptive MIMO schemes are considered for multiple antenna MB-OFDM system. The first investigated technique is adaptive antenna selection which selects the proper number of transmitting antennas using estimated SNR. And the second technique is adaptive modulation which can be used after the adaptive antenna selection is executed. By using these adaptive techniques, the reliable and high data-rate communications which are well adapted to the various user's demands and channel conditions are achieved.
