抄録
内容記述 高速移動環境下で想定される時間-周波数分散通信路では、シンボル間干渉(ISI)とキャリア間干渉(ICI)の低減は信号のパルス形状に依存する.陪直交周波数分割多重(BFDM)は自由なパルス設計ができることから、当通信路に対して有効な変調方式である.よってBFDMは時間-周波数制限性の良いガウスパルスを用いることができる.しかし、ガウスパルスの形状は全ての通信路で最適であるとは限らない.本稿では、通信路に対する最適なガウスパルス形状を、パルスの不確定性関数の比を最大にすることで行う.シミュレーション結果より、提案手法はガウスパルス形状の最適化に有効であることを示す. In highly mobile environments assumed time-frequency dispersive channels, reducing intersymbol interference(ISI) and intercarrier interference (ICI) depends on the signal pulse shape. Biorthogonal Frequency Division Multiplexing (BFDM) is an efficient modulation in terms of designing pulses flexibly. So BFDM can use Gaussian pulse which is a time-frequency well localized. However, the Gaussian pulse shape is not optimized in every channel. In this paper, we optimize the Gaussian pulse shape against the channels by maximizing the ratio of the ambiguity function of the pulses. Numerical result show that the proposed method is effective for the optimization of the Gaussian pulse shape.
