Comparative Study Of Suboptimal Algorithms For Tone Injection

Orthogonal Frequency Division Multiplexing(OFDM) is a very powerful system but having a drawback of peak to average power ratio (PAPR), which leads to a significant reduction in performance and power efficiency. Tone injection (TI) is a distortion less technique that can reduce PAPR efficiently without incurring data rate loss or extra side information. However, TI requires an search over all combinations of possible constellation. Tone injection when applied alone results in computational complexity. This paper discusses the three suboptimal algorithms namely cross entropy, tabu algorithm and aggressive clipping that help in reducing computational complexity and compares them.
