The primary receiver, the Relay, and the secondary receiver receive the primary signal, while the Relay and the primary receiver receive the secondary signal.
In the second transmission phase, the primary receiver and the secondary receiver receive a weighted linear composite signal which is transmitted by the Relay.
In the first transmission phase, the primary transmitter transmits the primary signal x p, while the primary receiver, the Relay, and the secondary receiver receive the signal, respectively.
On the receiver side, we assume that the secondary receiver can receive over all sub-channels simultaneously, for simplicity.
The secondary receiver decodes the received bit streams and places them into a packet structure in order to forward them to the higher layers.
Application of the ARQ protocol at the data link layer facilitates retransmission of the erroneous packets received at the secondary receiver.
On the other hand, at the secondary receiver (SR), by exploiting the received signals in two phases, SIC is employed to decode the desired message.
In the second transmission phase, x R is broadcasted and received by the primary receiver, the secondary receiver, and the relay input.
The received signals at the primary receiver, the Relay, and the secondary receiver are denoted by y 11, y 21, and y 31, respectively, which can be expressed as: {y}_{a1}=sqrt{p_p}{h}_a{x}_p+{n}_{a1} (1).
Every ball I got, I was the secondary receiver.
Typically, defenses place their "shutdown" cornerback alone on a secondary receiver, while doubling coverage on the best opposing pass-catcher.
