摘要: This paper presents a new blind equalization technique based on predictive filter structure with infinite impulse response (IIR). The resulting is an evolution of former proposals where only finite-impulse (FIR) predictors were used. proposed optimized the constant modulus criterion in robust to phase errors. algorithm (PCMA) offers low computational complexity and excellent performance radio channels high degree dispersion. Simulations results also show that stability verified practical situations.
