Description: As a multi-carrier modulation scheme, Orthogonal Frequency Division Multiplexing (OFDM)
technique can achieve high data rate in frequency-selective fading channels by splitting a
broadband signal into a number of narrowband signals over a number of subcarriers, where
each subcarrier is more robust to multipath. The wireless communication system with multiple
antennas at both the transmitter and receiver, known as multiple-input multiple-output
(MIMO) system, achieves high capacity by transmitting independent information over different
antennas simultaneously. The combination of OFDM with multiple antennas has been
considered as one of most promising techniques for future wireless communication systems. Platform: |

Description: The inherent robustness of OFDM against
multipath effects makes it an excellent choice for situations
where multiple transmitters are used simultaneously (to avoid
shadowing effects) and a path difference to the receiver exists.
One of the major disadvantages of an OFDM based system is
the characteristic high crest factor of the time domain signal.
In traditional RF based systems, this usually necessitates a
transmitter with a high dynamic range and hence results in
reduced power efficiency. In the proposed optical LED system,
this disadvantage is turned to an advantage - the time domain
OFDM signal is used to modulate (IM-DD) the optical source. Platform: |

Description: Synchronization in OFDM
With its robustness against multipath fading, orthogonal
frequency division multiplexing (OFDM) has become
the modulation of choice for many modern wireless standards.
However, OFDM is very sensitive to offsets in frequency and
time. This makes synchronization an essential part of an OFDM
system. This paper aims to motivate and analyze past work on
OFDM synchronization techniques. Platform: |
