| Abstract | Wireless communication in confined metal environment such as rectangular metal cavity has attracted more and more attentions recently. The channel characteristics in such an environment are different from those in the traditional wireless communication environments: extremely rich multipath components make communication very challenging. Multiple input multiple output (MIMO) plus ultra-wideband (UWB) technique is promising for wireless communication in confined metal environment, since it can fully employ radio resources not only in space domain but also in frequency domain. This paper considers the fundamental limit about MIMO UWB channel in rectangular metal cavity when different spectrum-shaping schemes such as water filling, constant power water filling, time reversal, channel inverse, constant power spectrum density and minimum mean square error are employed at the transmitter. Meanwhile, the measured channel transfer function is used in this paper for analysis. |
