ABSTRACT:
A method, system, and device are provided for increasing the total amount of useful information transmitted in a radio communication system. The method includes receiving a selection signal with which a cluster is selected; receiving data streams of information from at least two subscribers so that the streams have identical characteristics; dividing the data streams into a plurality of bit streams in order to form bit groupings through the selection of at least one bit from each one of said bit streams, for the purpose of carrying out the allocation of a state to each one of the groupings formed. Each state is associated with the cluster selected. Thereafter, the components that define the states are transmitted using orthogonal frequency division multiplexing (OFDM).
