    摘要： A wireless receiving apparatus generates an N′×B′ weight matrix W whose columns are orthogonal to each other by decomposing an estimated N′×M′ channel matrix into the N′×B′ weight matrix W and a B′×M′ matrix containing two or more non-zero matrix elements in each column, where B′ is an integer less than or equal to N′-1 and greater than or equal to M′. Alternatively, the wireless receiving apparatus generates a combination of an N′×B′ sub-weight matrix W1 and at least one second sub-weight matrix, where the product of the sub-weight matrix W1 with the at least one second sub-weight matrix is equal to the weight matrix W. The wireless receiving apparatus performs receive beamforming on received signals of N′ receiving antennas using the weight matrix W or the sub-weight matrix W1. The wireless receiving apparatus then performs a BP algorithm using receive-beamformed signals.

    摘要： An inexpensive ion sensor catalyst capable of detecting hydrogen phosphate ions in water and determining hydrogen phosphate ion concentration on the basis of oxidation current density for the ions, along with an ion sensor and a quantification method, the ion sensor catalyst being characterized by providing higher detection sensitivity than conventional ion sensor catalysts, being capable of maintaining high detection sensitivity over a wide range of hydrogen phosphate ion concentration, achieving a proportional relationship between concentration and oxidation current density, so that the concentration can be determined with accuracy regardless of the concentration range, and allowing oxidation current to reach a steady-state value in a short time, so that time to determine current density is short, resulting in shortened time to quantify hydrogen phosphate ions, and stable response to hydrogen phosphate ion oxidation can be made repeatedly.
