Energy Efficient Methods of Increasing Data Rate for Ultra Wideband ( Uwb ) Communications Systems

280 Abstract— This paper investigates energy efficient methods of increasing data rate for m-ary pulse position modulation (PPM) of impulse-based ultra wideband (UWB) systems in a multipath environment. The data rate of m-ary PPM can be increased by decreasing the pulse repetition interval (PRI) and/or increasing the number of bits transmitted per symbol… (More)
