The 1680 subcarriers are divided into 60 subchannels
, each of which includes 24 data subcarriers and 4 pilot subcarriers.
sensing time slots and the optimal transfer power to each subchannel
. The analytical and numerical results obtained in this paper clearly show that the maximal throughput can be achieved when the sensing time slots and the transfer power are both optimized.
the public, and the content transmitted on any dedicated subchannel
Figure 7 shows that the gate is now located at the bottom part of the left subchannel
and the gas injection point at the bottom wall of the part near the plastic injection point.
is a physical resource block (PRB) with a bandwidth of B.
The authors in  use the Shannon capacity formula to get the achievable instantaneous data rate on the subchannel
n through the link (i,j,k) in a time-slot with system state s as
The code is based on current literature of subchannel
analysis models and its accuracy is validated against experimental and calculated data reported for two reactors with plate type fuels.
where [P.sub.i][k], [SNR.sub.i][k], and [C.sub.i][k] denote the power, the signal-to-noise ratio (SNR), and the channel capacity on the kth subchannel
of the ith SISO channel, respectively, where SNR can be easily calculated with the help of feedback CSI according to (1).
The authors in  propose a green resource allocation scheme to jointly optimize the subchannel
assignment, power allocation and phase duration assignment, in which both the separate-downlink (DL)-and-uplink (UL) and mixed-DL-and-UL relaying assignments and the linear block diagonalization (LBD) technique are adopted.
A numerical simulation (subchannel
and CFD analysis) and an experimental investigation were applied mostly for the calculation of the thermal and hydrodynamic processes of the BWR [16-20,24] but not for the channel type reactor RBMK-1500.
By separating the problems into two, subchannel
allocation and power allocation, a convex programming conversion was achieved and suboptimal solutions realised.
OFDM systems use a great number of orthogonal subcarriers to transmit information; hence, the data rate on each subchannel
is much less than the system data rate .
