correlator for the horizontal and vertical components of codes 111111111 and 010101010, respectively.
where we have taken the [??]
correlator from [36] and used the fact that one-point functions vanish.
Although the systems does not require separate time slot to send the information bearing signal which increases the bit rate, this advantage is defeated by the low BER performance of the system due to multiple intrasignal interference terms in the
correlator output.
The FPGA is programmed with 15 GPS
correlators (channels), no acquisition unit is implemented due to its hardware complexity.
The
correlators for the KAT telescope are currently in two special containers nearby.
For a large number of particles in Brownian motion, the correlation function is an exponential decaying function of the
correlator time delay [1, 2]:
The first part is a bank of
correlators that correlate the received signal with the N spreading codes.
Then, the [[theta].sub.k] is equal to zero in (2) and
correlator output is [y.sub.k,k] = 1, ..., 20(N + 1).
"The Trunk Mains
Correlator is the latest product from Gutermann for finding leaks on large diameter pipes and across distances of up to 1km.
The smaller element spacing also leads to an increasing in
correlator quantity, as shown in Table 1.

Consequently, ALMA is home to the world's highest-altitude special-purpose supercomputer, the "ALMA
correlator." The
correlator is powered by 134 million processors, which together can compute at 17 quadrillion operations per second.
The outputs of each
correlator are weighted to provide a better estimate of the transmitted signal than is provided by a single component.
The
correlator and bit-timing block retains the original code and acquires timing and phase reference during the reception of each frame preamble.
