Thus, one instantaneous measurement or cycle consists of an ensemble of instantaneous individual antenna complex channel responses obtained through cross-correlation between a transmitted pseudorandom sequence and an identical, internally generated sequence in the receiver.
It corresponds to modeling the narrowband transmission between a transmit and a receive antenna as the sum of a large number of contributions with random and statistically independent phases, directions of departure, and directions of arrival [Par00].
It should be noted that for the cooperative schemes proposed in the literature that are based on full CSI at the BSs, the feedback load is given as bits per OFDM symbol since users need to feedback one complex-valued number per subcarrier per channel between a transmit and a receive antenna.
The time-domain detection technique uses a decision rule that is derived from a time-domain correlation between the transmitted and received SCI, and as a consequence, eliminates the need for channel estimation at the receiver.
TWT is determined from a correlogram estimated by a cross-correlation between the transmitted and returned signals.
To obtain the range and relative velocity of the reflecting object, it first achieves an element-wise multiplication between the transmitted and received frequency-domain symbol matrices.
However, the actual throughput is measured as the number of bytes transmitted between the time a distinguished segment is transmitted and acknowledged, divided by the time it takes to get the acknowledgment back.
Indeed, the degree of concordance at HLA A, B, and DR loci differs significantly between transmitting and nontransmitting serodiscordant couples.
As given in [25] and [27], the free space component, H LOS, of the complex response between a transmitting element m and a receiving element n (assuming that both elements are isotropic) is given as (phantom {dot {i}!}e^{-j beta d_{n,m}}/d_{n,m}) where β is the wave number corresponding to the carrier wavelength λ and it is given as (beta =frac {2pi }{lambda }).
The main concept is that the relay forwards a function of the superimposed received symbols and that an isomorphism exists between the transmitted codewords and the symbols mapped onto a lattice.
