How Cross domain signal analysis in LTE Regarding cross domain analysis, we see that, I traditionally signal from a receiver RF section can be demodulated and Q components using analog techniques. Today, however, the down conversion signal is digitized by an ADC IF, and usually then fed into the section of the baseband demodulation and … Read more
Basic Test for LTE Transmitter and Receiver Design LTE already requires fundamental changes in the base and handset and research project due to higher data rates, there is an important signal bandwidth and enhance integration and miniaturization in mobile phones, for example: Need to handle 6 different channel bandwidth from 1.4 to 20 MHz, and … Read more
EPS provides the user with a PDN IP connectivity for Internet access and for the operation of services such as Voice over IP (VoIP). An EPS bearer is usually associated with a QoS. Multiple carriers may be set for a user, in order to provide different QoS flows and connectivity to different PDNs. For example, … Read more
The LTE related core network evolution is referred to as Evolved Packet Core (EPC). LTE architecture is based on the system architecture evolution (SAE) model defined by the 3G Partnership Project (3GPP). EPC consists of the following network elements: Mobility Management Entity The Mobility Management Entity (MME) is the LTE mobility management and session management … Read more
CN (SAE called EPC) is responsible for the overall monitoring of the UE and the establishment media. Main logical nodes of the EPC are: PDN Gateway (P-GW) Serving GateWay (S-GW) Mobility Management Entity (MME) Evolved Serving Mobile Location Centre (E-SMLC) In addition to these nodes, EPC also includes other logical nodes and functions like a … Read more
