1. A transmitter, comprising:
a mapper configured to map data bits and power information to N subcarriers to obtain mapped information, wherein N is an integer larger than 1;
a first-level modulator configured to receive at least a first part of the mapped information and convert the at least the first part of the mapped information into at least a first part of subcarrier specifications, the subcarrier specifications including a complex number that defines an amplitude and a phase of a subcarrier;
a first orthogonal subcarrier generator configured to receive the at least the first part of the subcarrier specifications, and configured to generate a first baseband real signal (a first BB Re signal) and a first baseband imaginary signal (a first BB Im signal) that include at least a first part of the N subcarriers;
a first second-level modulator configured to receive the first BB Re signal and the first BB Im signal and to multiply the first BB Re signal with an in-phase intermediate frequency (IF) sine wave and to multiply the first BB Im signal with a quadrature IF cosine wave to obtain a first IF I signal and a first IF Q signal; and
a first beam former configured to receive the first IF I signal and the first IF Q signal and to modify a phase and/or an amplitude of the first IF I signal and the first IF Q signal to obtain a first directed IF I signal and a first directed IF Q signal and to modify the phase and/or the amplitude of the first IF I signal and the first IF Q signal to obtain a second directed IF I signal and a second directed IF Q signal.
