Title:
直交周波数分割多重化移動通信システムでピーク電力対平均電力の比を減少するための送/受信装置及び方法
Document Type and Number:
Japanese Patent JP4046728
Kind Code:
B2
Abstract:
A block coding apparatus and method in an OFDM mobile communication system are provided. They reduce PAPR to 3dB or less, while increasing a traditional block coding rate by a factor of 2, by use of complementary sequences. Therefore, spectral efficiency is improved by a factor of 2, maintaining the traditional error correction capability, and thus decoding is facilitated.
