As the consumer demand for higher capacity, faster service, and more secure wireless connections increases, new enhanced technologies have to find their place in the overcrowded and scarce radio frequency (RF) spectrum. Ultra-wideband (UWB) technology can offer a promising solution to the RF spectrum drought by allowing new services to coexist with current narrowband systems. On the other hand, this coexistence brings the narrowband interference (NBI) problem for UWB systems due to their very low power spectral densities. To meet increasing requirements for low cost, low power, flexible, and reliable wireless multimedia networks, an adaptive NBI suppressing method employing space-time adaptive processing (STAP) with receive diversity is discussed and experimentally investigated for direct-sequence (DS) UWB systems. Analytical results show that, in wireless home environments, the investigated scheme is capable of significantly improving the performance in combating NBI, compared with the conventional temporal approach. The effect of receive diversity is also examined via the Monte-Carlo simulations
