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: 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: |

Description: ABSTRACT
In this paper, the design and implementation of OFDM system along with Multi-Point Square Mapping combined with PTS (M-PTS) technique has received much attention in reducing the high peak to average power ratio (PAPR) of Orthogonal Frequency Division Multiplexing signals (OFDM). As compared to C-PTS technique, the proposed M-PTS technique needs not to submit side information but keeping almost the same performance of PAPR reduction as the C-PTS technique. A detailed Simulation of OFDM system is conducted and implemented using FPGA to validate the results. Platform: |
