"On Capacity of Gaussian \´Cheap\´ Relay Channel"

In this paper, we derive the capacity of Gaussian degraded \´light\´ relay channel having nodes using lights radios which possesses the most practical limitations and properties of time division duplex (TDD) technique of communication. The achievability is proved by using superposition encoding and successive decoding techniques. The converse is derived using the min-cut max -flow theorem for networks with light nodes. Our work of capacity analysis shows that even with light radios, the cooperative coding is beneficial and has the advantage of capacity over direct transmission.
