The minimum delay achieved between reception and retransmission is 13 pulse repetition intervals (PRI).
Accurate synchronization should be implemented to achieve robust reception of the DVB-T2 signal.
Under low traffic conditions (i.e., packet generation rate <2.0), both JRS and ZigBee achieved good reception rates.
Because LAB-25 provides a degree of contention that is sufficient to avoid single hop broadcast failures, it achieves broadcast reception rates of almost 100%%.
Because SB-1024, GD, and LAB-25 provide a CW that is large enough to avoid single hop broadcast failures, they achieve broadcast reception rates of almost 100%%.
When SLM is implemented, it is customary for a conventional SLM-OFDM receiver to perform some form of side information (SI) estimation because this SI contains critical information, which must be determined to achieve successful reception of payload data [10 13].
This piece of work, representing the first step of a wider study, is focusing on the modifications which may be required in the DVB-S2 standard (to be employed in the forward link) in order to achieve reliable reception in a challenging environment such as the railway one.
This is clear from the definition of the outage probability, which says that the system could get in outage once the SNR at the destination goes below a predetermined outage threshold γ out or, equivalently the system is unable to achieve adequate reception.
For example, it is aired across three different TV channels in Australia and, the most recent seasons have achieved their best reception yet.
A common concern for broadcasting algorithms in VANETs is their inability to achieve a packet reception rate close to [5].
An artefact (the repeat alert, fig 2) had been designed, which formalised and supported the "alertness" expectation, helped to achieve consistency between reception staff when applying judgment in uncertain situations, and formally designated the management of uncertainty as doctors' work.
