Abstract [en]

NOVELTY - A data stream is partitioned at a transmitting node into at least two data sub streams which undergo beam forming before being transmitted over a first link to the respective relay nodes. At least one restorable representation of the received sub stream from each relay node is forwarded over a second link to at least one receiving node where the representation is decoded and multiplexed to form an output signal corresponding to the data stream. USE - For wireless communication system. ADVANTAGE - Provides improved relaying scheme in communication system. Enables spatial multiplexing with improved spectrum efficiency. Allocates power between transmitter and relays with decreased power consumption and reduced generated interference. Enables cooperative relaying with increased overall system capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (A) a communication system; (B) a transmitting node; (C) a relay node; and (D) a receiver node. DESCRIPTION OF DRAWING(S) - The figure is a schematic flow diagram of the cooperative relaying method.
