Abstract |
|
|
| Due to its robustness to multipath fading and high spectral utilization efficiency, Orthogonal Frequency Division
Multiplexing(OFDM) is a very attractive technique for high rate wireless data communications, however, the main drawback of it
is the high peak-to-average power ratio(PAPR) of the OFDM signal. In this paper, the iterative companding transform technology is
presented to reduce PAPR, what kind of method is the optimal is obtained through the simulation that not only compare to the original
PAPR, the PAPR of different companding transform rate, and the iterative companding transform PAPR, but also the BER performance
of several methods. |
