1. A method, comprising:
- transforming a digital word into linked words according to a linking algorithm, wherein each linked word represents a corresponding portion of the digital word, and wherein the linked words are M-bit words, M being an integer; and
from a transmitter, successively transmitting each of the linked words as a symbol in a time slot selected from a plurality of at least 2M time slots according to a binary value of the successively transmitted linked word wherein a receiver is enabled to recover the digital word from the transmitted linked words according to the linking algorithm.

Abstract
An ultra low power, low complexity, low collision, deterministic modulation method that also works as a massive medium access mechanism for communication systems is based on positioning data in a communication resource space, such as time and frequency, such that the position of a symbol in that space determines its value and its access to the medium. The number base of the symbol is determined by the size of the subset of the resource space it is positioning itself in and, thereby, a few sparsely located symbols can convey a large value, while the remainder of the space can be simultaneously and massively used by other sparsely resource using members of the network.
