上記電力算出手段によって算出された電力の最小値がゼロになるようオフセット除去するステップと、
上記逓倍されたサンプリング周波数における各サンプリング点の中で電力の最小値を検出するステップと、からなり、
上記検出ステップによって検出されたサンプリング点に対応した通し番号と基準となる値との差を算出することによってタイミング調整行いシンボル同期を確立する、
ことを特徴とするシンボル同期確立方法。 A symbol synchronization establishment method in a receiver, comprising:
Generating an oversampled received signal at a sampling frequency multiplied by a symbol frequency;
Calculating delay detection of the received signal for each sampling point at the multiplied sampling frequency;
Calculating power from the delay detection result of the received signal calculated by the calculating means;
Removing the offset so that the minimum value of the power calculated by the power calculation means becomes zero;
Detecting a minimum value of power among each sampling point at the multiplied sampling frequency, and
Adjusting symbol timing and establishing symbol synchronization by calculating a difference between a serial number corresponding to the sampling point detected by the detection step and a reference value;
The symbol synchronization establishment method characterized by the above-mentioned.
