A Modified Coding Technique For High Peak-To-Average Power Ratio Reduction
نویسندگان
چکیده
Orthogonal Frequency Division Multiplexing System (OFDM) suffers from the problem of high peak to average power ratio reduction (PAPR). It is studied that Golay complementary codes (GCC) can provide codewords with low PAPR. However, the usefulness of this coding technique is limited to the OFDM with a small number of subcarriers. With the help of certain theorems and definitions, this paper discusses a modified GCC technique to combat the effect of high PAPR and achieve higher code rate and information rate for 16QAM OFDM system. KeywordsGCC, OFDM, PA, PAPR, QAM, RGCC.

A Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems
In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
