Abstract
Recently, IEEE 802.15.4a has specified a UWB PHY for low-rate
commutation with ranging capability for wireless personnel area
and sensor network applications [1]. Related work is reported on
low-rate energy-efficient UWB radios [2-4]. However, they are not
fully standard compliant or localization enabled. 802.15.4a supports
three bands of operation, i.e., sub-1GHz band (249.6 to
749.6MHz), low band (3.1 to 4.8GHz) and high band (6.0 to
10.6GHz) with 16 channels in total. A combination of the burst
position modulation (BPM) and binary phase shift keying (BPSK)
is adopted. With different coding rate, bursts per symbol, and chips
per burst, the mean pulse repetition rate (PRF) could vary from 3.9
to 62.4MHz for data throughput of 120kHz to 31.2MHz. This work
presents an UWB RF transceiver which supports 12 channels,
variable date rate, and ranging capability as specified in
IEEE802.15.4a.
