where the states [H.sub.0] and [H.sub.1] denote the PU's absence and presence, respectively, [x.sub.l] (m) is the PU's signal with the power of [p.sup.x.sub.l], [n.sub.l](m) is the Gaussian white noise with the power of [[sigma].sup.2.sub.l], [h.sub.l] is the subchannel
gain between the PU and the SU, and [M.sub.l] is the number of sampling nodes.
number of subchannels
simultaneously, the bandwidth access formula would
The objectives of the experiments were to achieve completely hollow cross sections with uniform wall thickness in both subchannels
, and part-to-part consistency.
where B is the bandwidth of each subchannel
, [b.sup.(k).sub.m,n] is also an allocation indicator variable, namely, [b.sup.(k).sub.m,n] = 1 indicates that subchannel
k is allocated to SUE n in the mth small cell; otherwise, [b.sup.(k).sub.m,n] = 0 .
is divided axially in control volumes.
where [Y.sub.j][k] and [N.sub.j][k] denote the vectors of received signals and noise from two symbol periods on kth subchannel
at the jth receiver.
Each combination corresponds to one product of one incoming and one outgoing subchannel
To make the model manageable and easier to analyse, only two concentric rings are considered, meaning that there are two parallel queues, each served by multiple servers (subchannels
Instead, a more efficient method is to pool together the available bandwidth for several subchannels
and apply active variable bitrate (VBR) encoding per subchannel
in order to increase overall picture quality and free up bandwidth for the channels that need it most at any point in time.
We denote [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the subset of nodes simultaneously transmitting at some time instant over a certain subchannel
. Most of the paper is dedicated to analysis of how to reduce I([v.sub.i], [v.sub.j]), that is, radio interference.
(1) Intercoverage interference discovery (a) Through RSSI measurements, each MS detects nearby stationary sensors activating on the same subchannel
. (b) For each of the occupied subchannels
, each MS sorts the interference degree from the stronger to the weaker.
Co-Layer interference occurs in downlink when the signal is transmitted from the serving FMC to the target UE and is not strong enough compared to the interference coming from the neighbors FMCs to the target UE, when the serving FMC and the neighbor FMC are transmitted at the same subchannel
