Power optimization of superimposed pilot for downlink short-packet transmission in IIoT
The industrial internet of things (IIoT) has great potential in achieving automation and intelligent production. However, existing networks struggle to meet the low-latency and high-reliability communication requirements in industrial control scenarios. Motivated by this fact, the power allocation p...

| description | The industrial internet of things (IIoT) has great potential in achieving automation and intelligent production. However, existing networks struggle to meet the low-latency and high-reliability communication requirements in industrial control scenarios. Motivated by this fact, the power allocation problem of superimposed pilot (SP) for downlink short-packet transmission in IIoT was studied and a lower bound for achievable transmission rates with imperfect channel state information and maximum ratio transmission was derived. Furthermore, the downlink weighted sumrate maximization problem was formulated and transformed into a geometric programming problem aiming to optimize pilot and data power allocation via successive convex approximation method. Simulation results demonstrate the superiority of the proposed power optimization scheme of SP in short-packet transmission. |
