نویسندگان
چکیده
Orthogonal frequency division multiplexing (OFDM) has been an effective technique to combat multipath fading in wireless communications. It has been successfully used for HF radio applications and has been chosen as the standard for digital audio broadcasting and digital terrestrial TV broadcasting in Europe and high-speed wireless local areas networks. In this paper an overview of a multiple carrier modulation technique known as OFDM (Orthogonal Frequency Division Multiplex) is given and discusses the problems, and some of the potential solutions, in implementing an OFDM system. Keywords— OFDM, BER, WLAN, DAB.

متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
