Abstract
An equalization method includes carrying out frequency domain conversion of M received signals into a 2M received vector having 2M elements, carrying out channel estimation and noise/interference estimation based on the 2M vector, calculating a 2M channel vector and a (2M)×(2M) noise/interference matrix, selecting a 2M−1 or less channel vector from the calculated 2M channel vector, selecting a (2M−1)×(2M−1) or less noise/interference matrix from the calculated (2M)×(2M) noise/interference matrix, calculating a 2M−1 or less equalization coefficient vector as equalization coefficients based on the selected 2M−1 channel vector and the selected (2M−1)×(2M−1) noise/interference matrix, selecting a 2M−1 or less received vector from the 2M received vector, and equalizing the selected 2M−1 received vector by using the calculated. equalization coefficients.
