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.

The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabilities.
The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the system’s
processor bus, providing faster data transfers
between the processor and peripherals. The PCI Local
bus also addresses the industry’s need for a bus standard
which is not directly dependent on the speed,
size and type of system processor. It represents the
first microprocessor independent bus offering performance
more than adequate for the most demanding
applications such as full-motion video.(The PCI Local bus concept was developed to breakthe PC data I/O bottleneck and clearly opens the doorto increasing system speed and expansion capabilities.The PCI Local bus moves high speed peripheralsfrom the I/O bus and places them closer to the system sprocessor bus, providing faster data transfersbetween the processor and peripherals.
