Pcc-ofdm with Reduced Peak-to-average Power Ratio
نویسنده
چکیده
Polynomial cancellation coded orthogonal frequency division multiplexing (PCC-OFDM) with overlapping symbol periods is a modulation technique which overcomes many of the disadvantages of OFDM. PCCOFDM is much less sensitive to frequency offset and Doppler spread than OFDM. PCC-OFDM like OFDM has a high peak-to-average power ratio (PAPR). In this paper it is shown that the PAPR can be reduced without increase in out-of-band power by using a new clip and filter technique. Results are presented for the new system in a two path multipath channel and for the case of frequency offsets. The PAPR can be reduced to 6dB or lower with little increase in bit error rate.

Selective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...
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...

| The authors propose a very eeective and exible peak power reduction scheme for Orthogonal Frequency Division Multiplexing (OFDM) with almost vanishing redundancy. This new method works with arbitrary numbers of subcarriers and unconstrained signal sets. The core of the proposal is to combine partial transmit sequences (PTS) to minimize the peak{to{ average power ratio distortionless.

Space frequency block code orthogonal frequency division multiplexing (SFBC-OFDM) systems has inherit drawbacks of high peak-to average power ratio (PAPR) signals, and constellation shaping with trellis is a promising approach for reducing both peak power and bit error rate of SFBC-OFDM signals. In practice, reliability will improve in SFBC-OFDM by employing coded modulation. In this work, it h...
متن کاملPerformance Improvement of Ofdm System Using Papr Reduction
Orthogonal frequency division multiplexing (OFDM) signals have a generic problem of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of the OFDM signal. The drawback of the high PAPR is that the dynamic range of the power amplifier and digital-to-analog converter during the transmission and reception of the signal is higher. As a resul...
