Rejection of interference from a nearby body area network (BAN) becomes significant in BAN applications, where a number of BANs are operating in the near vicinity of each other. Two interference rejection combining (IRC) techniques, optimum combining (OC) and Weiner-Hopf (WH) solution, are applied to the on-body wireless communication channels, and a more robust interference rejection technique, applicable...
A multi-user MIMO channel is characterized by multiple degrees of freedom that can be alternatively exploited for increasing the link quality through diversity or improving the achievable data-rate through spatial multiplexing. A convenient trade-off between diversity and multiplexing gain is achieved by multi-user orthogonal space-time block coding (OSTBC): an independent space-time code is employed...
The ability of impulse radio to resolve a large number of multipaths in a dense frequency selective channel suggests only a marginal improvement in performance by the use of multiple antennas from a diversity perspective. Furthermore, the small size of UWB receivers for in-home or sensor networking would result in a very high correlation among antenna elements, reducing even more the exploitable diversity...
