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 .
Each
subchannel 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's SNR.
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.
