PAPR Reduction in OFDM Systems: Zadoff-Chu Matrix Transform Based Pre/Post-Coding Techniques
High Peak to Average Power Ratio (PAPR) is one of the major drawbacks in Orthogonal Frequency Division Multiplexing (OFDM). The high PAPR increases the complexity of Analogue to Digital (A/D) and Digital to Analogue (D/A) converters and also reduces the efficiency of RF High Power Amplifier (HP...

description |
High Peak to Average Power Ratio (PAPR) is one
of the major drawbacks in Orthogonal Frequency Division
Multiplexing (OFDM). The high PAPR increases the
complexity of Analogue to Digital (A/D) and Digital to
Analogue (D/A) converters and also reduces the efficiency of
RF High Power Amplifier (HPA). In this paper, we propose
two novel PAPR reduction techniques for OFDM systems,
Zadoff-Chu matrix Transform (ZCT) precoding based
PAPR reduction technique and ZCT postcoding based
PAPR reduction technique. Simulation results show that, at
clip rate of 10-1 , the PAPR of our both proposed systems
reduced to 0dB, 3dB, 4.1dB and 4.3dB for M-QAM (where
M = 4, 16, 64, 256). Both ZCT precoding and postcoding
based OFDM systems are shown better PAPR gain and Bit
Error Rate (BER) performance than Walsh Hadamard
Transform precoded OFDM (WHT-OFDM) and OFDM
conventional. |
