Super-position alignment techniques for digital communication

Abstract

Techniques are described to perform digital communications. An example method of digital communication includes obtaining, by a first node, an input bit sequence c = [c0, c1,..., cK-1]; determining, by the first node and based on operation (s) performed on the input bit sequence c, a first intermediate bit sequence w = [w0, w1,..., wNw-1] and a second intermediate bit sequence w'= [w'0, w'1,..., w'Nw'-1]; determining, by the first node, a superimposed bit sequence h = [h0, h1,..., hH-1] by performing a middle-alignment superposition operation on the first intermediate bit sequence w and the second intermediate bit sequence w'; determining, by the first node, an output bit sequence f = [f0, f1,..., fF-1] from the superimposed bit sequence h; and transmitting, by the first node, a signal including the output bit sequence f to a second node.
