Adaptive blind channel identification and equalization methods of two types MIMO-OFDM systems based on subspace are discussed. The proposed method employs reduced-rank orthogonal iteration to estimate noise subspace with low computational complexity. Oversampling autocorrelation matrix is applied to obtain redundant information, when the number of transmit antenna is greater than that of receive antenna...
65 Zn was used as a radiotracer to study the sorption characteristics of zinc by two calcareous soils from Gansu Province (China). The sorption and desorption isotherms of Zn on two untreated calcareous soils and on two soils treated to remove CaCO 3 were determined at 20±2°C, pH 7.8±0.2 in the presence of 0.001 mol/l CaCl 2 . The contribution of CaCO 3 to the Zn sorption...
