LTE Parameters and Downlink Modulation LTE (Long-Term Evolution) utilizes various parameters and downlink modulation schemes to optimize data transmission over the wireless network. LTE parameters and frequency bands What is OFDMA? OFDMA multiple access and downlink frame structure OFDMA transmit and receive chains Here are some important parameters and downlink modulation techniques used in LTE: … Read more
Here I write about a simulation analysis of the system performance deterioration caused by the following four types of interference: eNodeB->UE, UE->eNodeB, eNodeB->eNodeB, and UE->UE when two systems share the eNodeBs. During simulation, it is assumed that the time percentage of the interference occurrence is 100%, that is, interference is always there. From simulation result … Read more
Assume that the eNodeB receiver’s IF bandwidth is Bw (unit: MHz), and the eNodeB receive noise figure is Nf (unit: dB), The equivalent noise level of the eNodeB receiver is as follows: No = –174 + 10 log (Bw) + Nf (Unit: dBm) If the demodulation carrier-to-interference ratio C/I (unit: dB) of the eNodeB receive … Read more
Here I write down about How to UE Distribution and Channel Model : Pedestrian vs High Mobility, TDD Specific Uplink and Downlink Configuration and Power Boosting Configuration selection during initial planning of LTE Network and why it needs to take care by radio engineer during LTE network plan. UE Distribution and Channel Model: Pedestrian vs … Read more
