total propagation delay will equal the sum of the delays
Considering a node equipped with an equidistant line array composed of M antenna elements, the distance between the signal source and the antenna array is far enough, and [[theta].sub.i] and [[tau].sub.i] represent DOA and propagation delay of the multipath signal, respectively.
The comparison is done in terms of power consumption, propagation delay and Power-Delay Product (PDP).
where [n.sub.i] is the index of the initial sample for the first transmitted LTE frame, [s.sup.S.sub.F] is the number of samples per LTE frame, [[tau].sup.l] is the propagation delay for the lth frame, which depends on the distance between the receive antenna mounted on the train and the transmit antenna at the eNodeB, [??]*[??] denotes the round operation, [f.sub.s] is the sampling frequency, and [e.sup.l] is an integer error term which depends on the actual channel and the noise.
The propagation delay is measured based on the distance between the transmitter and the receiver and the speed of light.
where [t.sub.aux] is the mean delay of auxiliary switches taken from correction table [s], [l.sub.hf] is the header length with preamble, SFD and CRC (208 bits) [bit], [l.sub.pt] is the length of the ping test frame [bit], R is the net bit rate [bit/s] and finally the optional tsp signal propagation delay [s].
Since the high-to-low ([t.sub.PHL]) and low-to-high ([t.sub.PLH]) propagation delays associated with these transitions are not usually equal, the average propagation delay is given by
In [9], the impact of large signal propagation delay on various UASN MAC schemes is evaluated.
The propagation delay of various types of mixed CNT bundles as discussed above was calculated based on the expression given in (15).
Therefore, the proposed scheme improves the network stability and video quality by reducing the packet loss and increasing the throughput even a long end-to-end propagation delay. It also provides smoothed playback by preventing buffer underflow or overflow.
To evidence the accuracy of the proposed numerical model in function of n, we rely on the SI parameters, propagation delay [T.sub.p] and signal attenuation [alpha]([t.sub.0]).
Synchronous early-completion-prediction adders (ECPAs) [1], also known as variable-latency adders [2], have been introduced for high clock rate and high-precision datapaths, as they allow single-cycle operations even if the clock period is shorter than the worst-case carry propagation delay. Tanks to the data dependency of actual carry chain propagation, the occurrence of multicycle operations can be maintained statistically rare, thus allowing an overall speed improvement.
