Analysis of Various Strategies for Improvement in Performance of OFDM Systems

Presently a days, there is colossal request of high information rate in order to suit tremendous number of clients. This need has additionally prompted the prerequisite of change in the present wireless advancements. As OFDM is the physical layer in the majority of the present wireless systems. This paper exhibits various ways in which the performance of OFDM system can be improved. The performance parameter varies with the type of application. In case the demand of application is accuracy, BER (bit error rate) should be low but the receiver circuitry becomes more complex to decode complex channel coding techniques. In addition to make the communication more reliable, precoding techniques can be concatenated with channel encoding techniques.
