This paper investigates the information theoretic capacity of Pulse Position Modulation (PPM) Ultra Wideband (UWB) communications for single user channels. The capacity is evaluated for a Rake receiver based on uniform sampling and single bit sampling quantization. This Rake architecture denoted as the Single Bit Rake receiver (SBR). The propagation channel is modeled with a link impulse response with delay spread and Inter Pulse Interference (IPI). Capacity per pulse of SBR is developed as a function of pulse density and number of rake fingers. A comparison of information theoretic capacity of SBR is studied for the case of single pulse and multiple repeated pulses per symbol.
