Abstract
を取得する信号復元モジュールと、上記信号復元モジュールの出力の復調及び復号を行い、ビット情報を出力する復調復号モジュールと、を含む。従来の検出方法に比べて、上記システム性能は、実現複雑度を考慮する際に向上する。
Description
受信された信号をr=Hs+nであると仮定する。
ここで、Hは、N×Mチャネルマトリックスであり、sは、M次送信信号ベクトルであり、rは、N次受信信号ベクトルであり、nは、N次独立白色ガウス雑音であり、M及びNは、アンテナを送受信するシステムの個数である。
この線形検出と比較して、この非線形検出技術は、動作複雑度を増加させてもシステム性能を効率的に向上させることができる。
これは、検出過程で雑音増加を確実に減少させるのであろう。同時に、従来の線形検出アルゴリズムと比較すると、このようなシステムの複雑度は、確実に増加されなかった。この複雑度は、順次干渉除去非線形検出アルゴリズムよりはるかに低い。
