This paper describes a monolithic integrated single-chip transceiver intended for impulse radio (IR) — Ultra-wide Band (UWB) applications compliant to the IEEE 802.15.4a standard. The transceiver operates in the higher UWB band on four different channels, which fit into the European spectral mask (defined by the ECC). In accordance to the standard, several data rates up to 27.24 MB/sec have been implemented...
The paper proposes a modification of the hybrid PPM/BPSK modulation described in the IEEE 802.15.4a Impulse Radio Ultra-Wideband (IR-UWB) Physical Layer (PHY) specifications. Proposed modulation is intended for reception by the coherent IEEE 802.15.4a IR-UWB PHY receivers; it considerably reduces the distance between PPM positions compared to the IEEE 802.15.4a IR-UWB PHY specifications. In this way,...
