A Hybrid Path Loss Prediction Model based on Artificial Neural Networks using Empirical Models for LTE And LTE-A at 800 MHz and 2600 MHz

Abstract: LTE's peak data rate for downlink and uplink can reach 326.4 and 86.4 Mbps, respectively [2], while LTE-A significantly enhances these specifications: it increases peak rates, achieving 3 Gbps for downlink and 1.5 Gbps for uplink; for such, it requires a bandwidth up to 100 MHz [3].A Hybrid Path Loss Prediction Model based on Artificial Neural Networks using Empirical Models for LTE And LTE-A at 800 MHz and 2600 MHz Bruno J.

“…It has been shown in [25] that expert knowledge (modelaided learning) can be embedded into wireless systems for optimization. Additionally, such hybrid-based models have shown to be effective for path loss prediction as documented in [26]. In this work, the proposed DL model uses a simple path loss model for assisting in the learning process.…”

“…Fifth generation cellular networks (5G) offer unprecedented bandwidth and faster network speeds by tapping into a high band spectrum in the mmWave frequency range, typically from 30 to 300 GHz [12,13]. Propagation is more lossy in the mmWave bands when compared to today's microwave bands, thus the solution is to modify the standard path loss models (with a frequency between 28 and 38 GHz) to fit the real world measured propagation data for reliable mmWave channel planning [14,15]. However, the previous models (Okumura, COST-Hata) do not work with frequencies between 28 and 38 GHz, and thus they are not compatible with the 5G [16,17].…”

“…While some obstacles absorb and others reflect the radio signal; similarly, they all limit the transmission ability of signals ( Figure 2) [6]. 9.2° and 49.7° half-power band width (HPBW) antenna at receiver (RX) [14][15][16]. The measurement propagation [14][15][16] combines power delay profiles (PDPs) for single point angles using high directions (8,19).…”
