Abstract

See full text

A wireless communication method in a wireless communication system which includes a radio transmitting station apparatus having a plurality of antennas and a radio receiving station apparatus having an antenna and which performs transmission and reception of a radio signal with a single carrier. The wireless communication method includes: estimating a communication path matrix based on a training signal; transforming the estimated communication path matrix into a frequency domain, transforming a complex conjugate transposed matrix of each of a unitary matrix and an adjoint matrix obtained by performing singular value decomposition for each frequency with respect to the transformed frequency domain communication path matrix into a time domain, and adopting each as a reception weight matrix and a transmission weight matrix; performing transmission beam formation based on the transmission weight matrix; and performing reception beam formation based on the reception weight matrix.
