During WIT phase, the source transmits its symbol toward the intermediate relay simultaneously, the cooperative relay retransmits its decoded symbol to destination at the same time and bandwidth.
This provides a larger degree of freedom and significantly improves the rate since each transmitted message is decoded at the destination at the same subcarrier in a different transmission period.
Note that in this case it is possible of having two routes to the same destination at the same time (the converted path and the newly calculated proactive path).
In the first phase, the source transmits signals x = [x[2k] x[2k + 1]] T (E[x[n]] = 0, and E[x2[n]] = 1) with the transmit power ε s = ε sd = ε sr 1 = ε sr 2 to the relays and the destination at the same time.
In the MIMO RFID channel, whatever the signaling schemes are used, the signals from the tag antennas (analogy to the relays) arrive at the reader (analogy to the destination) at the same time slot, and this makes the two models significantly different.

We reach our destinations at the same time, but the amount of fuel used by these pedal punchers is probably twice what I use.
The Air Transport Association, according to its spokesman David A. Fuscus, put numbers through the computer in January 1998 and concluded that 99.5percentt of all checked bags reached their destinations at the same time as their owners.
Instead of members having to swap homes and destinations at the same time, or pay for a straight up rental, they can now pledge time in their property to a central bank, thus earning points that can be redeemed later to enable them to stay in other members' homes when they actually want go on vacation.
This comes with a couple of travel inconveniences compared to checking a pet as baggage: Pets must be dropped off three hours before flight takeoff at a different location than human travelers' departure point, and Delta says it can't guarantee that pets will arrive at their destinations at the same time as their owners.
Particularly, we design the new protocol that allows the source node retransmitting the signal to the destination node at the same time as the relay node forwarding the received signal to the destination node with an Alamouti coding scheme.
