[en] We present the design of discrete-phase sequences
considering simultaneously the peak sidelobe level (PSL) and avoiding
reserved frequency bands which are occupied by narrowband interferers
or communications. We use the coordinate descent framework and
propose an algorithm to design discrete-phase sequences with spectral
power suppressed in arbitrary bands and with low auto-correlation
sidelobes in terms of PSL. Our proposed algorithm exploits fast
Fourier transform and is, therefore, computationally efficient. The
over-the-air experiments using implementation on software-defined radio
show reasonable agreement with numerical simulations and feasibility for
field-deployment
