PAPR Reduction in OFDM: A Technological Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Earlier signals were sent in analog domain, but in these days signals are sent in the digital domain. Additionally, single carriers are substituted by multicarrier for the purpose of better transmission. Nowadays multicarrier systems are commonly implemented. Some multi carrier systems are Orthogonal Frequency-division Multiplexing (OFDM), Code-Division Multiple Access (CDMA) and many others. OFDM is one of the best and attractive techniques. Its sub carriers are place orthogonally to each other and are utilized to carry the data from the transmitter to the receiver. In this system, guard band is present which deals with the issue of ISI and noise is lessened by greater number of sub carriers. But the large Peak – to – Average Power Ratio of these signal have some undesirable effects on the system.
