Abstract:
High data rate and speedy communication has become the ultimate goal of any
communication research work. Multiplexing of signal bits is an important part of the
wireless communication system. OFDM (Orthogonal Frequency Division
Multiplexing) has become a promising technique at present days wireless
communication technology due to its extraordinary features.
This thesis paper represents a total overview of OFDM system, basic principles of
OFDM system, OFDM generation and reception. Though it has some salient and
supreme features over other multiplexing techniques, still has some drawbacks which
limit its performance in some cases.
So an investigation has been done to minimize the effects of these drawbacks,
specially emphasis is put on to reduce the PAPR (Peak to Average Power Ratio) of
OFDM signals. Several techniques to minimize PAPR has been investigated and
finally some new techniques have been proposed to minimize PAPR.
