Abstract :
A direct sequence design is proposed for impulse radio ultra-wide bandwidth systems to suppress the mutual interference between ultra-wide bandwidth wireless and coexisting narrowband services. Notch frequencies are created in the ultra-wide bandwidth signal spectrum at bands where narrowband services operate. The direct sequence design has low computational complexity and can be easily implemented in practical systems. Numerical results are provided to show that the direct sequence design can significantly suppress the mutual interference between ultra-wide bandwidth and narrowband services and highly enhance the integrity of both ultra-wide bandwidth and narrowband systems.
