Firstly, for each calibration point, the vector of the mean received power from all the transmitters is defined as ( {boldsymbol{upmu}}_{mathbf{Prx}}left {gamma}_{mathrm{curr}}right)=left{{mu}_{{Pr mathrm{x}}_1}left {gamma}_fright),{mu}_{{Pr mathrm{x}}_2}left {gamma}_fright dots right} ).
(4) Convergecasting with signal quality aggregation: By adopting the MRC signal processing technique, the SNR at the receiver is the sum of the contributed SNR from all the transmitters.
where ({boldsymbol Psi } triangleq mathrm {E}{mathbf {y}_{mathrm {r}}mathbf {y}_{mathrm {r}}^{H}} = sum _{k=1}^{2K}mathbf {H}_{k}mathbf {B}_{k}mathbf {B}_{k}^{H}mathbf {H}_{k}^{H} + sigma _{mathrm {r}}^{2}mathbf {I}_{N_{mathrm {r}}}) is the covariance matrix of the signal received at the relay node from all the transmitters.
On the contrary, in the case of the PoS (62), equality can be observed whenever p(‡, b) = p(⊤, b) and (33) holds with equality, which is the case when there exists an equilibrium where every transmitter uses a different channel from all the other transmitters.
In CDD [11] a single data stream is sent from all transmitter antennae with a different cyclic delay applied to each replica, effectively resulting as if the original stream was transmitted over a channel with increased frequency diversity.
In this figure, the local mean path loss is obtained from all the 8 transmitters and all the local areas in the scenario.
where P0 d0) is the received power from the link source located at distance d0, N0 is the power noise spectral density, B the channel bandwidth, and Pint is the total interference power at the link receiver, i.e., the sum of the instantaneous received powers from all the undesired transmitters.
where is the instantaneous received power (dimension: [W]) at distance, is the noise power spectral density of the noise (dimension: [W/Hz]), is the channel bandwidth, and is the cumulated interference power (dimension: [W]) at the receiver, that is, the sum of the received powers from all the undesired transmitters.
