Minimize Power Ratio (PR) in OFDM Using Tone Reservation Method

Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high-speed data transmission over multipath fading channels. One the major issues in OFDM is a large ratio between peak and average power, which affects Power Amplifiers in terms of complexity. A lot of techniques have proposed to reduce the power ratio but transmitted power, bit error rate (BER), etc. are so high. In this paper, combined SLM and proposed Tone Reservation methods are performed to reduce for power ratio between peak and average. Proposed Tone Reservation is the best suitable technique, based on BER and CCDF performance of the system.
