cooperative communication
hi all,
im confused about mimo and cooperative comm. what i understand is in mimo, multiple antenna transmit chunks of independent data simultaneously, creating a spatial multiplexing and increase the transmission rate. and in cooperative comm, single antenna terminals cooperate thus create 'virtual mimo system'. somehow, the signals received at destination are replicas of same signals degraded by different channel. on the other hand, in mimo, the receiver demux the signals received (chunks) to recover the original.
so is mimo and cooperative comm is comparable then? how difference is the receiver/detection method for both mimo and cooperative comm, since both receive multiple signal, different chunks of ori signal (mimo) and multiple versions of the ori signal (cooperative comm).
im just confused since almost all literature saying cooperative comm is like 'virtual mimo'.
pls help..
thanks a lot!!
