… SUBOPTIMAL SCHEMES By using the above scheme, we can calculate the optimal power
allocation policy that maximizes the transmission capacity of the CR user while keeping the …

… power allocation schemes approach equal power assignments. It can be observed that the
… power allocation schemes further, we define the relative gain of the power allocation as …

… tion scheme with a source, an amplify-and-forward relay, and a destination. We examine the
possibilities of power allocation (PA) over the subchannels in frequency and space domains …

… develop the optimal power allocation schemes in closed form by employing the feature of
the NOMA principle for the two problems. Furthermore, the power difference between NOMA …

Interference alignment (IA) is a promising technique for interference management and can
be applied to spectrum sharing in cognitive radio (CR) networks. However, the sum rate may …

… power allocation scheme which can be applied to both downlink and uplink NOMA scenarios
with two users. This power allocation … expression for the power allocation factors can be …

… Then we consider a power allocation scheme that allocates the transmission power such …
tonically decreasing function of power, this scheme always allocates additional power to the …

… The main objective of this paper is to investigate the optimal power allocation scheme for
sum throughput maximization of the NOMA system with α-fairness constraints. In existing …

… For such a system, we investigate relay and power allocation schemes such that the … as
the total power consumed for transmission. We show that joint relay and power allocation is a …

… different power allocation schemes. … power allocation schemes. We train different DNNs
by feeding the same channel realizations as inputs and the different results of power allocation …
