DWellsThesis
This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance dierence between the classications of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements.

Key Problem: Timing assumption
during prelayout synthesis widely
differs from the post layout reality.
• This happens because the
interconnect delay dominates the
overall propagation delay in DSM
(Deep Sub‐Micron) technologies.
• As a result getting a timing closure
becomes a challenge

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.
