For wireless broadband communication long-term evolution (LTE) is a standard for also mobile devices and data terminals, by using different radio interface together with core network improvements LTE increases the capacity and speed of mobile network. In this paper radio frequency receiver of radio-frequency long-term evolution (RF-LTE) is design and simulated using MATLAB Simulink, where the design based on illustrating parameters of each stage in LTE RF receiver from generating LTE waveform to error vector magnitude (EVM) measurements, where simulation results with 8 MHz bandwidth the transmitted signal power -3200 dBm, the received signal power (-140 to -160) dBm, while the demodulated signal reaches to -60 dBm difference between main loop and side loop witch lead to high confident recovered signal, also complementary cumulative distribution function (CCDF) measurements applied on output signals so that computes the power of complementary for cumulative distribution CCDF function from signal in time domain. Where CCDF curve shows value of time that a signal stand still above the level of average power for the measured signal or the probability of signal power will be above the level of average power.

“…Table 2 shows the number of resource blocks against LTE-defined bandwidth [21]. Since RSRP is considered as a key parameter during the HO process, the (4) shows how the RSRPP is calculated [22], where Ptx is transition power, Pl is path loss, and Ls is additional shadow fading. The ( 5) and ( 6) described the calculation of path loss of macrocell and femtocell, respectively, according to 3GPP [23]- [25], where d is the distance between user and base station in meters and fc is carrier frequency in MHz.…”

“…Bai et al [10] studied velocity and quality of service (QoS) for evolved node B (eNB) and femtocell handover to minimize unnecessary handoff. The UE velocity is categorized into three classes (0-15), (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and (>30) km/h to prevent unsuccessful calls. The algorithm neglects services that are not in real-time.…”

High-speed mobility system has now become a serious concern for mobile operators due to the large frameworks of a heterogeneous network made up of multiple cell types and different frequency bands. Handover (HO) is conducted in a real-life scenario when the user equipment (UE) moves from one network coverage to another by performing proper measurement with high speed. HO breakdown and call loss are observed due to a high speed; thus, high-speed mobility system needs improvement by using the UE speed as one of the key measurement monitoring criteria for the long-term evolution (LTE) network. Vendor consultation has been considered in this paper in addition to real drive test measurement in highways. Results have shown that velocity has a direct impact on the handover quality and overall timing. Results also demonstrate that 120 km/h measurement is better than 140 km/h as UE speed.

“…An important feature specific to the LTE standard is the Orthogonal Frequency Division Multiplexing (OFDM) technology, which uses and distributes the high-speed data stream over multiple orthogonal carriers, rather than a single wideband carrier. For the LTE standard IOP Publishing doi:10.1088/1757-899X/1254/1/012009 2 used in the current 4G networks the minimum transmit unit is a resource block with a duration of 0.5ms occupying 180 kHz comprised of 12 sub-carriers 15kHz wide [3][4]. This technique brings many system advantages including spectral efficiency, reduced inter-symbol interference by addition of a cyclic prefix [5], and reduced delay propagation.…”

This paper presents preliminary research for the implementation and testing of a Software Defined Radio (SDR) sensor with electromagnetic spectrum monitoring capabilities for measuring signals specific to the Long-TermEvolution (LTE) mobile communications standard. The proposed sensor is developed on the ADALM Pluto SDR platform - and is designed to acquire a bandwidth of at least 20MHz. To determine the spatial extent of the measurements, the sensor also includes a GPS (Global Positioning System) module. The hardware control of the sensor is performed both in stationary variant using a laptop and in mobile mode using a low-cost module - Raspberry Pi. Present findings suggest that the designed SDR solution represents a reliable and low-cost alternative for real-time spectrum monitoring of wideband signals like the case of 4G-specific signals. The cost of the whole implemented monitoring system is about EUR 330.
