碩士 === 國立高雄第一科技大學 === 電腦與通訊工程研究所 === 102 === Partial transmit sequence (PTS) technique is effective to reduce peak-to-average
power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signals
technique. PTS is used to reduce PAPR effectively with linear operation and does not
have destructive and interfered effect for the OFDM signal itself. Without considering
noise effects, the received signal can be demodulated perfectly at receiver end. The
Pseudo-random partition scheme has the best PAPR reduction performance but comes
with very high complexity, which is the problem we are going to solve for in this thesis.
In this thesis we proposed three novel subblock partitioning schemes for PTS
based PAPR reduction of OFDM signals: the Geometric Series Division (GSD), the
Bidirectional Geometric Series Division (BGSD), and the Quadratic Permutation
Polynomials (QPP) Based Index partition schemes. For GSD, a special geometric series
are used for data assignment and this genomic series is a power of 2 increments. For
iii
BGSD, two sets of geometric series are used for data assignment, one series is a power
of 2 in ascending series, and the other group is a power of 2 in descending series. For
the QPP based index method, it uses the new values from the QPP interleaver as an
index pointing to the locations of the data in each subblock. And then, the adjacent
partition method is used for data assignment. The three division methods above not only
overcome the problem of PAPR and have the PAPR performance close to that from the
Pseudo-random partition scheme without high complexity like the Pseudo-random
scheme. Finally, the numerical simulations are carried out to verify that our proposed
methods can effectively solve the problem of high complexity and to reach the PAPR
reduction performance.
Key words: peak-to-average power ratio (PAPR), partial transmit sequence (PTS),
Pseudo-random, Adjacent partition; complexity, Geometric Series, Quadratic
Permutation Polynomials (QPP).
