【摘要或目录】：This paper addresses the problem of interfering with
narrowband licensed users caused by DS-UWB systems.
Deducting the colliding frequency band from UWB spectrum, and
then employing orthonormal expansion by Hermite-Gaussian
functions, the paper develops a low-complexity algorithm for
generating DS-UWB signals that adaptively avoid or recover
arbitrary colliding bands. A system implementing this algorithm
is suggested. Performance comparison with matured seventh
Gaussian derivative shows that our system achieves about 1.5dB
signal-to-noise gain and 52.2dB signal-to-interference gain over
the referenced system in AWGN environment.
