The phrase "a random scheme" is correct and usable in written English.
It can be used when referring to a plan or method that is chosen without any specific criteria or purpose.
Example: "The team decided to implement a random scheme to select participants for the study, ensuring a diverse sample."
Alternatives: "an arbitrary plan" or "a haphazard approach".
We consider several relaying strategies in this article, including a best selection scheme, a random selection scheme, and a scheme where all decoding relays participate.
The mechanisms provide higher allocative efficiency than a fixed price system, are almost competitive with a standard scheduling heuristic which assumes non-strategic agents, and can sustain a substantially larger number of vehicles at the same per-owner fuel cost saving than a simple random scheme.
Therein, a RS procedure, allowing only a randomly chosen subset of sensors to acquire the measurement, is coupled with both a TDMA scheme and a random access scheme.
Patients were randomly assigned to one of the four treatment groups using a computer-generated random scheme.
These findings indicate that genetic progress in growth can be achieved without a significant decline in fitness, at least in the short term, provided that a family mating scheme, rather than a random mating scheme is adopted.
These results show that the smart selection scheme is much better than the random scheme, yielding a lower percentage of bad choices and a higher average cooperative capacity gain; additionally, this gain never decreases as the cooperation range increases.
In this section, we introduce a random beamforming scheme for the downlink NOMA multiuser system with limited CSI feedback.
It is based on a hierarchical design: (1) with full-duplex communications, operation of subchannels is decoupled, and a CSMA/CD-like protocol is implemented in each subchannel as a random access scheme; (2) on top of random access per-subchannel, a simple but effective subchannel selection scheme is executed locally on each client to harvest multi-user diversity.
