Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier
transmission technique that becomes the best choice in wireless
high-data-rate transmission. The drawbacks of OFDM are high
Peak-to-Average Power Ratio (PAPR) and sensitivity to frequency offset.
High PAPR decreases the amplifier’s efficiency. The simplest PAPR
reduction method is clipping, but it gives in-band and out-of-band
distortion that degrades the performance of the system. There are
various types of clipping, such as classical clipping, deep clipping,
and smooth clipping. This paper analyses the use of low-density
parity-check (LDPC) codes as an error correction coding (ECC) for those
various types of clipping. The simulation results show that classical
clipping gives the best performance in PAPR reduction and error
