“…In this context, in the study proposed in this paper it is designed a HI Monopole-type antenna to cover 100% of the DVB-T standard band, and the bands of LTE-450 and LTE-700 [13]. This project was developed so that the device, in a single structure, displays characteristics such as: ultra-wideband operation, low complexity design and simple geometry, compactness, lightweight and inexpensive fabrication that can be easily integrated into the housing of electronic equipment.…”

In this work, a compact ultra-wide-band microstrip antenna loaded with C-shaped parasitic elements, for Digital Video Broadcasting-Terrestrial (DVB-T) and LTE 450 / 700 signal reception, is designed and presented. The proposed antenna is named "HI Monopole", and its geometry has been designed to be simple, lightweight, and compact. Fabrication process is inexpensive and suitable for electronic gadgets. The HI Monopole operates with ultra-wide bandwidth characteristics, encompassing Digital Video Broadcasting-Terrestrial (DVB-T) standard (470-890 MHz), LTE-450 and LTE-700 bands. This feature has been accomplished by inserting an indent in its ground plane, adjusting dimensions of the feeding line, and adding two C-shaped parasite elements onto the region posterior to the antenna's main radiating element. It was verified via electromagnetic measuring that this device is capable of covering the 429-1022 MHz range. Hence, its total bandwidth is 593 MHz. The superior and inferior cutoff frequencies have been defined using the-10 dB return loss reference level. Therefore, the proposed antenna can be employed for receiving DTV and LTE signals broadcasted in any country, independently of its adopted standard.

“…While statistical analysis based on MCS would give ideal spectrum usage than analytical method since MCS uses a given realistic deployment scenario to establish a probability of interference between victim link and interfering link in the same band or adjacent band [7]. MCS uses a repeated random generation of victim link, interfering link and their parameters [3, 8, 9]. After numerous trials (i.e.…”

“…The MCS has also been used to study interference in [3, 8, 9, 11, 12]. The interference causes degradation of the performance on the victim link receiver system causing a reduction in the data transmission rate, especially for victim link receiver near the edge of the victim link transmitter coverage area [1, 4, 8, 13]. Interference has been recognized as a major bottleneck in increasing the capacity of a radio system and is often responsible for dropped calls [1, 2, 3, 4, 5, 11, 12].…”

“…There are a number of studies on interference and its mitigation methods to maintain a strategic distance from common Co-channel interference source in the radio system. MCS is one of such studies and has been used in the literature to study the co-existence between LTE and Digital broadcast in [3, 8, 9, 11, 12]. The authors in [3, 8, 9, 11, 12], presumed that the MCS offers the best performance in terms of examining complex interference than the analytical method.…”

Radio spectrum's sharing guideline is an essential component of spectrum utilization process. Since there is no insightful interference avoidance method in a radio system, the careful selection of sharing conditions is the only means for achieving successful co-existence and optimal spectrum usage in the radio system. Spectrum sharing rule can be obtained by an analytical method or statistical method. The analytical method considers the worst case scenario to calculate sharing rules. Nonetheless, this doesn't represent the lasting phenomenon amid ordinary task; moreover sharing rules may be unnecessarily rigid. Henceforth, the Monte Carlo Simulation (MCS) strategy has been utilized to establish a probability of interference based on a random distribution of victim link receiver in time and space with respect to victim link transmitters. The study has been done for cluster number N with values of 1, 3, 4, and 7 in a cellular system. Monte Carlo Simulation analysis showed the percentages of interference are 24.94%, 9.36%, 3.33%, and 0.4% for N = 1, N = 3, N = 4, and N = 7 respectively. In terms of throughput per total bandwidth per a single site, N = 7 offers a spectrum utilization of 1/7 and N = 4 offers a spectrum utilization of 1/4. Therefore, a relative enhancement in capacity of 7/4 has been achieved with 3.3% probability of interference which is below the threshold value of 5%.
