Abstract
The paper introduces a novel Ultra-wideband (UWB) communication system with SAW matched filters that can be operated with low power consumption. The system employs a unique pulse position modulation (PPM) method combined with spreading codes that are achieved by using SAW matched filters for modulation and de-modulation. The system also employs a unique spreading code to improve the ratio of desired correlation signal to undesired signals (D/U ratio) in this method. We fabricated 4-GHz SAW matched filters and used them in a UWB module comprised of these filters, low noise amplifiers, converters, base-band circuits and an antenna. With the UWB communication system, we achieved 20-Mbps real-time video streaming. The TX and RX power consumption in RF section were 50 mW and 150 mW, respectively. These results indicate that this system is suitable for a wireless personal area network (WPAN) that requires low power consumption.
