Description: PEAK TO AVERAGE POWER RATIO REDUCTION OF DM
SIGNALS USING PEAK REDUCTION CARRIERS:
ABSTRACT
A technique is described for a better than 5 dB reduction
in the Peak to Average Power Ratio (PAPR) of an OFDM
signal. The optimal amplitude and phase of additional
peak reduction carriers (PRC) is obtained using a codebook,
which is obtained using a search of all possible
signal combinations.-PEAK TO AVERAGE POWER RATIO REDUCTION OF OFDM

Description: The Interleaved Frequency Division Multiple Ac-
cess (IFDMA) scheme is based on compression, repetition and
subsequent user dependent frequency shift of a modulated signal.
Multiple access is enabled by the assignment of overlapping but
mutually orthogonal subcarriers to each user. In this paper it
is shown that IFDMA can be regarded as unitary precoded
OFDMA with interleaved subcarriers. On the other hand,
IFDMA is shown to be a CDMA variant with frequency domain
orthogonal signature sequences and chip interleaving. Thus, it
combines the advantages of single and multi carrier transmission
such as low peak to average power ratio, orthogonality of the
signals of different users even for transmission over a time
dispersive channel and low complexity. Simulation results show
the good performance of coded IFDMA transmission over a
mobile radio channel for different data rates. Platform: |

Description:
OFDM modulation produces higher Peak Average Power Ratio (PAPR) whenever the carriers in OFDM symbol add synchronously in the time domain resulting in higher signal power. This high power saturates the power amplifier placed in the RF section resulting higher bit error rate. To avoid this higher PAPR value the baseband IQ signal has to be pre-processed in the baseband before it is sent to RF Platform: |
