Multiple input multiple output radio channel characterisation for ultra wideband body centric wireless communication

Complete channel knowledge and its accuracy are the basis of an optimized system design. In this paper ultrawideband multiple input multiple output (UWB-MIMO) radio channel characterization for body centric wireless communication is being presented. Body shadowing and body obstruction limits the channel capacity. It has been observed that MIMO antenna technique provide significant increase in capacity for body-centric wireless networks (BCWN). Spatial correlation matrices (complex and power correlation) have been computed and it has been noticed that the correlation values are much higher, where antennas are located in line-of-sight scenario as compared to none-line of sight case. In addition to this, capacity comparison of MIMO antenna with single input single output (SISO) and single input multiple output (SIMO) antenna system shows significant improvement for MIMO case, which supports the applicability of MIMO in BCWN.
