| Summary |
In this paper, we discuss on the realization of reduced peak power
transmission for the OFDM systems. Since the signals have large amplitude
fluctuations in conventional OFDM systems, signals amplified by a
non-linear amplifier are greatly distorted, resulting in severe
performance degradation. In order to avoid this large amplitude
fluctuation, we propose a scheme for reducing the non-linear distortion by
using the set of the signal point series which show low
Peak-to-Mean-Envelope-Power-Ratio (PMEPR) value. In this system, one symbol
is transmitted with multicarriers and the received signal is detected with
maximum likelihood sequence (MLS) detection. |
