Abstract
A wireless communication method for use in a first wireless device. The method comprises performing a column wise dot product on each column of a first data matrix, to generate a second data matrix, performing an N point inverse Fast Fourier transform (IFFT) on each row of the second data matrix to generate a modulated data matrix, where N is a number of columns of the second data matrix, and transmitting, to a second wireless device, the modulated data matrix.
