Description: PAPR Reduction based on a Modified PTS with
Interleaving and Pulse Shaping method for
STBC MIMO-OFDM System.
It is with GUI. Using GUI we can see comparison with number of sub carrier, sub-block and over sampling factor as well BER plot comparison of normal and with PTS technique. You need to run MIMO_OFDM_with_PTS.m
Note: Do not delete or rename amy file and place all the files in one single folder because some are functions which are called in GUI code.-PAPR Reduction based on a Modified PTS with

Description: The objective of this thesis to implement and simulate the IEEE 802.16 OFDM
physical layer using Matlab in order to have better understanding of the standard and the system performance. This involves studying, through simulation, the various PHY

Description: Reduction of peak-to-average power ratio (PAPR) in
orthogonal frequency-division multiplexing (OFDM) system using
the partial transmit sequence (PTS) approach. In PTS, the total
search for the number of subblocks and the rotation factors must
be accomplished. As the number of subblocks and rotation factors
increases, PAPR reduction improves. The number of calculation
increases as the number of subcarriers increases, such that
complexity increases exponentially and the process delay occur
simultaneously. In this paper, a modified PTS scheme combined
with interleaving technique for PAPR reduction has been
presented. The scheme is very effective and avoids the use of any
extra Inverse Fast Fourier Transformations (IFFTs) as was done
in PAPR reduction by ordinary PTS technique when dividing the
various subcarriers into different subblocks. The simulation
result shows that PAPR performance is improved in comparison
with the modified PTS and computational complexity is reduced Platform: |
