Abstract

Efficient utilization of the extremely limited available power of impulse radio ultrawideband (IR-UWB) waveforms can significantly extend their wireless reach in the wireless transmission chain of IR-UWB over fiber (IR-UWBoF) systems. In this letter, the two most common types of photonically generated IR-UWB waveforms are considered and accurate closed-form analytical expressions for the bit rate—distance relationship in the wireless transmission chain of IR-UWBoF systems are developed. These analytical expressions are verified by simulations and optimized such that the wireless transmission distance of IR-UWB waveforms is maximized under the Federal Communications Commission spectral constraints.
