Abstract :
Cognitive radio(CR) technologies have recently received much attention. In this paper, we consider the interference of soft-spectrum adaptation (SSA) modulation ultra wide-band (UWB) to wireless local area network (WLAN). We investigate the effect of the interference to WLAN under the model and scenario proposed by TG 1/8 group. From the simulation, the proposed method has simple structure and shows good performance. By designing a proper pulse waveform and coding with high frequency efficiency according to the spectrum mask canceling the band of IEEE 802.11a, the interference by UWB will be minimize.
