After the sender finishes transmitting its packets to its own receiver, it starts to receive incoming appended packets that arrive in a collision-free packet train.
This was a touch awkward: because the model has no knowledge of the relationship between an e-mail's sender and its receiver, it provides the same suggested responses whether you are corresponding with your boss or a long-lost sibling.
In the scheme of IA, we only need to consider the subspaces occupied by the received signals, as shown in Fig. 4. For each receiver, it can receive nine signals, since K n =K n+1=3.
If the trasmitter has data to send to the receiver, it will determine its power bound according to the interference tolerance declared by the receiver's busy tone.
When a reply message is received by the DSRC receiver, it must be processed by encapsulation and the reply processed appropriately.
At the receiver, it is clear that to receive the message correctly, it is sufficient to successfully receive any two out of the three packets.
When the sender receives an ACK packet from the receiver, it stops sending the strobe sequence and sends the main packet immediately (Fig. 2).
Once the sender receives a feedback message from a receiver, it immediately updates the Has, Wants, and Uncertain sets of the receiver.
Because this scheme simply assumes that the received power levels from multiple transmitters are the same at the receiver, it adjusts the carrier phase offsets of transmitters, but does not coordinate the transmit power levels of transmitters.
The RXRA technique is also desirable in that the Distributed and Centralized schemes become equivalent; when a link maximizes its own capacity by changing reconfigurable antennas only at the receiver, it also maximizes network sum capacity.
