As shown in Figures 5, 6, and 7, respectively, by dynamically tuning the DyTSA ratio α ji to maximize the relay data transmission with different capacity on receiving and transmitting links, the maximum system throughput of CRNs can be achieved by applying the DyTSA scheme in contrast to the fixed scheme.
Thus the definition fails to distinguish between, for example, recording, copying, formatting, retrieving, transmitting, linking, and manipulating data.
where P r (i,j) denotes the interference power from link l j, and l j denotes the link concurrent transmitted with link l i at the same frequency.
where l j denotes the link concurrent transmitted with link l i at the same frequency.
The total number of MIMO streams transmitted by link e ′ and link e should not exceed the DoF K. 9.
To ensure that all transmitting links have a sufficiently large SINR, the following linear constraint is imposed: M l ( r ) 1 - x l ( r ) + G tr ( l ) re ( l ) P tr ( l ) x l ( r ) ≥ γ tgt ( r ) σ re ( l ) + ∑ n ≠ tr ( l ) G n re ( l ) P n y n, ∀ l ∈ L, ∀ r (26).
For illustration purposes, the thickness of the links reflects the amount of data transmitted, while dotted links are never active during the entire transmission.
The numbers in the middle of the direct links indicate the number of packets can be transmitted by these links in one time slot.
And it can enhance the throughput of transmit link.
This will increase traffic on selected links which may lead to congestion and hence data packets transmitted through these links may face additional delay.
