Wireless baseband transmission MIMO communication system
This paper investigates multiple input multiple output (MIMO) communication systems using wireless baseband transmission (WBT) scheme which directly transmits a baseband signal stream from an antenna without modulation techniques over an extremely wideband channel. Following to the previous paper discussing the fundamental idea and the feasibility of WBT experimentally, this paper deals with WBT MIMO systems. Some natures of WBT MIMO systems and the data transmission scheme are discussed theoretically, and two types of signal processing structure, i.e., a spatio-temporal beamformer with and without the cascade connection of a one-dimensional (1-D) FIR filter are proposed for the equalization of WBT MIMO channel. Transmission characteristics in the frequency-domain are obtained through a measurement in a radio anechoic chamber, and computer simulations are carried out using them. The results show the good performance towards equalization of a WBT MIMO channel.
