Efficient algorithms optimization for complex-valued signal estimation

  • 摘要: 該文討論了用于含噪復(fù)值信號(hào)功率估計(jì)的兩種結(jié)構(gòu)簡(jiǎn)單、計(jì)算高效、可具有預(yù)測(cè)特性、可保證輸出估計(jì)恒為正值的功率估計(jì)系統(tǒng)。功率估計(jì)的偏差和方差可以通過優(yōu)化設(shè)計(jì)FIR子系統(tǒng)來達(dá)到最小或減小。用于移動(dòng)通信CDMA系統(tǒng)功率控制的仿真表明:控制能力提高,低信噪比時(shí)系統(tǒng)差錯(cuò)率下降。
