Abstract |
The main problem of using OFDM system is high peak to average power ratio (PAPR). There are various methods available to reduce PAPR, some of them are distortion less and some methods cause distortion in original signal. Due to distortion actual data may get lost. Reducing PAPR by active constellation extension is one of the best method available. In this method, constellation points which contribute to high PAPR are extended. We can reduce the PAPR very effectively without disturbing the original signal & there is no need to send side information. This paper present algorithms to reduce PAPR using active constellation extension. | |||||||||
