where k 1 k 2 × 1 k 1 ∑ r = 1 k 1 log ( 1 + γ m k 1 | h r, d | 2 ) can be explained like this: the k1 parity check packets of the network code protect k2 broadcast packets of terminals i(R(i) = 1) equally, and the mutual information transmitted by k1 terminals (T i) = 1) provides uniform contribution to k2 broadcast packets.
In the weeks before our bailout, the entire trading floor sat slumped, watching computer terminals broadcast our demise.
The transmission through the network is conducted in two phases: in the first phase, the information is broadcast from the terminals to the relays simultaneously.
This paper presents two novel smart cross-layer error-control coding schemes for improving the error protection of service advertisements that are broadcast to mobile terminals on wireless billboard channels (WBCs) established over a digital video broadcast-handheld (DVB-H) infrastructure.
In the broadcast phase, each terminal broadcasts its own data (broadcast-packet) and the others which keep silent decode the received packets.
In the broadcast phase, each terminal broadcasts its broadcast-packet in its orthogonal channel while the others keep silent and decode what it hears, which is the same as that in ANCC.
In the broadcast phase, each terminal transmits its broadcast-packet in the orthogonal channel and all the others listen and decode what it hears.
In the proposed SSC-2W scheme, each of the two source terminals broadcasts its first symbol from the expanded constellation to the opposite source terminal and the relays in different time slots, i.e., the first and second time slots.
The key idea to apply network coding in this setup is that the relay broadcasts to the terminals a function, for example a bitwise XOR, of its received packets.
In the relay phase, for terminal i, if T i) = 1, it randomly selects d broadcast-packets of terminals {j1, j2,..., j d }, where j k ⊂ ℜ ( i ) and R (j k ) = 1(1 ≤ k ≤ d), XORs them from symbol by symbol and conveys the result to the destination in the orthogonal channel.
