hart-protocol
The HART Application Guide has been created by the HART
Communication Foundation (HCF) to provide users of HART products
with the information necessary to obtain the full benefits of HART digital
instrumentation. The HART communication protocol is an open standard
owned by the more than 100 member companies in the HCF. Products that
use the HART protocol to provide both analog 4–20 mA and digital signals
provide flexibility not available with any other communication technology.

Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage
power ratio (PAPR), which may severely affect the
power efficiency of RF power amplifiers. In this paper, we
propose a simple method to reduce the PAPR of MIMO-OFDM
signals based on the use of unused subcarriers. Instead of
processing the signals at each transmitter separately, a peak
cancelling signal is generated at one antenna and is then applied
to all the others with only simple modifications. Simulation has
shown that a minimum 2 dB reduction in PAPR can be achieved
for all transmit signals using this approach. As the signal
processing is nearly all done at a single transmitter, repetition of
the operations at each transmitter is avoided, and therefore the
overall cost of the system can be significantly reduced.
