Outage-optimal Relaying

In a slow fading channel, cooperation between wireless nodes can be used to increase diversity  by helping each other to relay information. The optimal relaying performance is characterized by the outage capacity of the channel. We analyse the outage capacity of a 3-node relay channel with independent Rayleigh-faded links and half duplex constraint , i.e.  the relay cannot transmit and receive at the same time.  We present optimal relaying strategies in both the high and the low SNR regimes.
