1. A Transmission method with linear amplification using nonlinear amplifiers performed by a transmitting apparatus comprising:a serial-to-parallel converter converting an input stream of bits into a parallel signal;
an antipodal converter electrically coupled to said serial-to-parallel converter and converting the bits ?n(1), . . . , ?n(?) into ? polar signals bn(1), . . . , bn(?);
a mapping, generator receiving the polar signals bn(1), . . . , bn(?) from the antipodal converter and generating M??M mapping sequences, where M? is the number of polar symbols in which a symbol from a generic constellation of dimension M is decomposed, defined by
where i=0,2, . . . , M?1, n is the order of the n-th symbol to transmit, m represents a auxiliary index with m=1, . . . ,?, M=log2(?) and ?(m,i) is a binary term of (?(??1,i), ?n?2,i), . . . , ?(1,i), ?(0,i)) which is the binary representation of i;a set of M? BPSK modulators, each one connected to each one of the outputs of the mapping generator, where each one of the M? polar components is modulated and multiplied by the corresponding complex coefficient gi, resulting for each branch of order i the signal
where n is the order of the element in the stream of symbols, r(t) is a pulse whose shape is selected to minimize envelope fluctuations, t represents the time, and T represents the time duration of each symbol;
a set of M? nonlinear amplifiers, with each one amplifier connected to the output of each modulator, that amplifies the signal and with its output directly connected to an antenna.
