Abstract
A method of modulating complex symbols is provided, which delivers a multiple carrier signal. The method performs the following acts for at least one base block of N×K complex symbols, where N and K are integers such that N>1 and K≥1: extending the base block to deliver a block of N×(2K−1) elements, referred to as an “extended” block; phase shifting the extended block, delivering a phase shifted extended block; filtering the phase shifted extended block, delivering a block of N×(2K−1) filtered elements, referred to as a “filtered” block; mapping the N×(2K−1) filtered elements of said filtered block onto MK frequency samples, where M is the total number of carriers and M≥N; and transforming the MK frequency samples from the frequency domain to the time domain.
