This translation involves converting the radio signal into a digital one that the computer can understand and then retransmitting, or streaming, it to online users.
Shaped like a giant, silver chocolate bar, the Slingbox sits on top of your television, takes in video feeds from cable or satellite set-top boxes, DVD players and PVRs, and then retransmits a video stream via a broadband internet connection to wherever you happen to be.
and then retransmits to both d1 and d2.
The AF relay [10] amplifies the received signal and then retransmits it to the destination.
With the mixed lattice codes at each relay, the relay amplifies the mixed lattice codes and then retransmits them to the destinations.
Non-regenerative relays employ amplify-and-forward (AF) scheme, which only performs linear processing of the received signal and then retransmits the signal to the destination.
At the contrary, HARQ-IR first transmits with a high coding rate, i.e., 4/5, and then retransmits additional redundancy bits if needed, which is more energy-efficient.
In the case of HD-MH two time slots are necessary per source message, as the relay listens first and then retransmits the signal to D. Since we assume the SDF protocol, R only retransmits if the received signal was decoded error free.
The detect-and-forward (DF) scheme is similar to the AF scheme, with the difference that the relay detects the transmitted symbols and then retransmits the sequence of detected symbols.
Likewise, either side may detect a lost packet, and then retransmitting of the missing chunks proceeds.
