Multiple access capacity in multipath channels of delay-hopped transmitted-reference UWB

The multiple access capacity of delay-hopped transmitted-reference (DHTR) ultra-wideband radio [R.T. Hoctor et al., May 2002, N. Vanstralen et al., May 2002] is investigated through analysis and simulation. The factor that limits the multiple access capacity of DHTR is the degree of multipath in the transmission channel.
