  abstract =     "Ultra wideband (UWB) technology is characterised by
                 transmitting extremely short duration radio pulses. To
                 improve its multiple access (MA) capability, UWB
                 technology can be combined with traditional spread
                 spectrum (SS) techniques. Existing spreading codes are
                 only optimal in additive white Gaussian noise (AWGN)
                 and their performance degrades in multipath fading and
                 narrow band interference. In this paper, we propose the
                 use of spreading codes obtained using a novel design
                 methodology based on genetic programming (GP) and DNA
                 computation for DS-UWB communications. The spreading
                 codes obtained by this novel design methodology
                 performs better than traditional spreading codes in
                 both AWGN and multipath fading. In addition, spreading
                 codes with desired spectral characteristics could be
                 designed to minimise the mutual interference between
                 the DS-UWB and co-existing narrowband systems. The
                 proposed design methodology is attractive for spreading
                 code in terms of performance and flexibility to design
                 spreading codes for a specific design criteria",
