In this section, we enhance this idea by introducing the use of multi-element arrays on the receiver side, in order to maximize the received signal's SNR.
The various components comprising the MSCR have been designed to maximize the received solar energy, the transfer of solar energy to salt, and the capacity of hot salt production.
For FHS, the selection is made at the source to maximize the received SNR at the relay.
However, if no CSI from the interferers can be obtained, MRC is the optimal solution to maximize the received desired signal power.
The precoders can be designed to alleviate multiuser interference, maximize the received desired signal power, or minimize the MSE of the received signals.
The precoding weights for the transmit antenna array operation are determined from a quantized set by the UE and serve as beamforming to maximize the received SINR.
But in strong synapses, the A subtype, which is more sensitive, crowded into the center while B was pushed out to the periphery, as if to maximize the receiving cell's ability to pick up that robust signal.
Waveform design and diversity in radar networks to maximize the receiving power was studied in [5].
As proved in [7], the optimal weight vector, which is necessary to maximize the receiving SNR, is obtained by phase steering: ω k [ n ] = h k [ 1, n ] H h k [ 1, n ],..., h k [ M, n ] H h k [ M, n ] T. (5).
There are M RRH ports, subcarrier n is assigned to user k, and the sum power allocated to this subcarrier is μ k [n]P T, i.e., ∑ m = 1 M p k [ m, n ] = μ k [ n ] P T. To maximize the receiving SNR, the transmit power of RRH port m is (when the PCPP is not considered): p k * [ m, n ] = G k [ m, n ] ∑ m = 1 M G k [ m, n ] ⋅ μ k [ n ] P T, m = 1, 2,..., M, (19).
In other words, the cognitive relay first maximizes the received signal quality with maximal ratio combining and then precodes the received signal with a beamforming vector w to balance the received power at different cognitive destinations and reduce the received interference at primary users.
