Performance of Space-Time Block Coded MB-OFDM UWB Systems

Abstract

This paper presents two MIMO-MB-OFDM UWB systems which include the space-time block coded MB-OFDM (STBC-MB-OFDM) UWB and convolutional space-time block coded MB-OFDM (CCSTBC-MB-OFDM) UWB. A series of experiments is conducted over the UWB channels with 2ISO and 2I2O configurations. Experimental results indicate that the 2I2O STBC-MB-OFDM is applicable to the real-time multimedia service in the general wireless digital home environment, and CCSTBC-MB-OFDM can be considered for the extremely adverse channel environment.
