Abstract

Methods and systems that enable a cooperative form of transmission performed by a set of asynchronous transceivers operating as a distributed joint communication system. In an embodiment of the method of this invention, information is transmitted from one or more predetermined nodes (the source nodes) in the network. The information is received at the other nodes (the receiving nodes) in the network. For every information symbol/codeword each of the receiving nodes receives an accumulation of signals from nodes transmitting an earlier stage. At each of the receiving nodes a predetermined criterion is utilized to decide whether to retransmit the received information. If retransmission is indicated, the signal modulating the information symbol is retransmitted from the receiving nodes and delivered to an increasing number of downstream nodes.
