1. LTE-packet.zip,In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below. ,578KB,downloads 13

8. PTSandSLM.rar,In this paper, we have proposed a new PAPR reduction
technique in MIMO-OFDM systems. It achieves the result
which proves the PAPR of 2¡Á2 MIMO-OFDM systems. The
parameters of the simulation are determined by standard IEEE
802.11n. From the simulation results, it is shown the proposed
method has better PAPR performance in this system.
Additionally, when the number of sub-blocks is increased, high
PAPR reduction performance can be obtained.,2KB,downloads 15

reduction to papr in ofdm with Peak Windowing:
The basic idea of peak windowing is to multiply the envelope of OFDM
signal with a weighting function . Therefore,
~xE (t)= xE (t) f (t)
The weighting function given by:
f (t)= 1-¦² ¦Á .w(t- t )
w(t) : is the window function.
t : denotes the position of a local maximum of the envelop xE(t) .
¦Á : attenuation constant .
When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal.
Hanning window function will be used for w(t)
As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.

High Peak to Average Power Ratio (PAPR) is still a
most important challenge in Orthogonal Frequency Division
Multiplexing (OFDM) system. In this paper, we propose a
Discrete Cosine Transform (DCT) precoding based SLM
technique for PAPR reduction in OFDM systems. This
technique is based on precoding the constellation symbols with
DCT precoder after the multiplication of phase rotation factor
and before the Inverse Fast Fourier Transform (IFFT) in
SLM-OFDM System.,229KB,downloads 104
