(1) Common messages: this type of message is usually when many vehicles transmit the same message, such as traffic reports or multimedia.
It takes ACO-OFDM more bandwidth than DCO-OFDM to transmit the same message, although ACO-OFDM is less demanding in terms of dynamic range requirement of the LED and power consumption.
Under a selective combining scheme used by MBMS over single frequency network (MBSFN), multiple MBMS group base stations may be scheduled to transmit the same message at the same time, at the same rate, using the same modulation/coding scheme (MCS), to produce MIMO-type gains at receiving client nodes.
The degree of benefit gained from the ability to make this shift may depend on whether the signal components in the two different channels are redundant or nonredundant: as discussed in question 1 above, if the components are redundant, then the animal benefits by being able to transmit the same message when switching to the other channel.
Wait 30 seconds or so then transmit the same message again.
Since this field is inside a loop, several signs (glosses) can be transmitted in the same message.
To minimize interference overhead, a node is regarded not to broadcast the same message twice if it comes from different transmitting nodes with a delay in time.
Thus, every node in the transmission range may compete to transmit the same priority message which causes the broadcast storm problem again.
Death glares convey the same message.
As the source and the relay are transmitting measurements of the same message u, we let A2=B.
In this way, the receiver is provided with multiple copies of the same message transmitted and the spatial diversity gain is introduced in the channel[2, 3, 9].
