Abstract:
|
This paper focuses on the interplay between
data throughput and battery duration in UWB units, both of
which the most perceptible at the user’ level. The potential
benefits of enlarging the power amplifier back-off (linearity)
are assessed for different channel conditions according to a
communication system following the IEEE 802.15. 3a
standard (MB-OFDM proposal). New performance results are
presented which highlight the kinds of channels where an
increase in transmit linearity (power amplifier back-off
enlargement) yields increased data throughput, and those
where it does not. Results show whether designs sacrificing
power efficiency have a benefit in data rate increase or it is
simply a power spoil (ineffective reduction of battery’s timeof-
life). |
