Device and method for improving the signal to noise ratio by means of complementary sequences

A method of transmitting a transmission signal, comprising:

• encoding the transmission signal, wherein said encoding includes:
• separating the transmission signal into a first plurality of substantially orthogonal component signals;
• each of the first plurality of substantially orthogonal component signals having one of a plurality of phases;
• convoluting the first plurality of substantially orthogonal component signals by a convolutor with a selected set of complementary sequences to create a second plurality of substantially orthogonal signals, each of the second plurality of substantially orthogonal signals having a phase corresponding to one of the plurality of phases;
• and
• summing each of the second plurality of substantially orthogonal signals having the same phase by an adder, to create a third plurality of substantially orthogonal signals;
• modulating the third plurality of signals into a single output;
• transmitting said single output over a network;
• receiving said single output;
• demodulating said single output into a fourth plurality of substantially orthogonal signals, said fourth plurality being of the same number as the first plurality and having phases corresponding to the phases of the first plurality;
• and
• decoding said fourth plurality, Wherein said decoding includes;
• separating each signal of said fourth plurality into a number of component signals, wherein, the number of component signals corresponds to the number of said complementary signals;
• and
• convoluting each of said component signals with an inverse of said selected set of complementary sequences to form a fifth plurality of signals and summing each signal of the fifth plurality of signals having the same phase to create a sixth plurality of signals.

An apparatus for encoding a transmission signal to improve the signal to noise ratio, comprising:

• a modulator for separating the transmission signal into a first plurality of substantially orthogonal component signals, each of the first plurality of substantially orthogonal component signals having one of a plurality of phases;
• a convolute for convoluting the first plurality of substantially orthogonal component signals with a selected set of complementary sequences to create a second plurality of substantially orthogonal signals, each of the second plurality of substantially orthogonal signals having a phase corresponding to one of the plurality of phases;
• and
• an adder for summing each of the second plurality of substantially orthogonal signals having the same phase, to create a third plurality of substantially orthogonal signals.
