چکیده
We present an OFDM frequency synchronization scheme. This paper presents an extended solution for the carrier frequency synchronization problem of OFDM. The scheme uses number of bits, modulation level, cyclic prefix, FFT size similarly to the algorithm proposed by Tilde Fusco [21].The proposed scheme attains considerably higher accuracy than the scheme by [21] requiring convolutional encoding data and viterbi decoding technique. Pilot Insertion and Cyclic Extension also included in the synchronization scheme. Our proposed method gives better results for different values of signal to noise ratio. Keywords– Bit error rates, convolution, cyclic prefix, fast Fourier Transform, Orthogonal Frequency Division Multiplexing, SNR (signal to noise ratio), Synchronization, viterbi algorithm.

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...
