Abstract(in English) | One of the major drawbacks in the design of OFDM systems is its higher peak to average power ratio (PAPR) in the time domain signal. Although Partial Transmit Sequence (PTS) method is proposed as one of the solutions to reduce PAPR, this method is required to inform the phase control information of PTS to the receiver for the correct demodulation of received data information. On the other hand, in the time varying fading channel it is indispensable for the correct demodulation of received data information to estimate the channel frequency response for every symbol by using the pilot subcarriers inserted in the data symbols. This paper proposes a novel PTS method which employs the pilot subcarriers at the receiver both for the detection of phase control information of PTS and for the channel estimation in the time-varying fading channel. This paper demonstrates the effectiveness of the proposed method by the various computer simulation results. |
