Gigabit LTE

Gigabit LTE – definition, class, technology, devices, availability Gigabit LTE is an important springboard for mobile 5G data connectivity. It contains a number of building blocks for the new network. Gigabit LTE is an advanced form of LTE, the 4G radio technology that mobile operators use to connect mobile devices. Gigabit class lte what is … Read more

Different Categories of UE in LTE

Different Categories of UE in LTE Categories of UE in LTE is divided by its function which is as per below. Functionality: eNB obtains the UE radio capabilities via: • The S1AP initial setup request message • The X2AP in case of handover • The RRC in any other cases eNB sends the UE radio … Read more

Single and Multiple User MIMO in the Uplink SU MIMO LTE

Single and Multiple User MIMO in the Uplink SU MIMO LTE SU-MIMO is within LTE, but at the time of this writing has not yet been fully identified. To implement the SU-MIMO UE require two transmitters. This is an important problem from the standpoint of cost, size and battery consumption, and for these reasons, SU-MIMO … Read more

Affects of the Channel in LTE MIMO

Affects of the Channel in LTE MIMO To understand the impact of the channel, let’s assume that the base station receiver is facing many challenges in the same MIMO receiver that universal areas, but also must receive data simultaneously from multiple users. In terms of MIMO UM, each signal is derived from a separate UE, … Read more

Multi-antenna Techniques LTE to improve the downlink performance

Multi-antenna Techniques LTE to improve the downlink performance There are five methods of multiple antennas have been defined for the LTE downlink to improve the performance: Receive diversity at the mobile Transmit diversity using SFBC at the eNB (evolved Node B) MIMO spatial multiplexing at the eNB, for one or two users Cyclic Delay Diversity … Read more

The MIMO channel Matrix

The MIMO channel Matrix Consider for a moment in time, on the same frequency and channel modeling as a black box with durable internal components. If we add two completely different input signals is to be mixed with each other in a certain manner depending on the value of Z1 to Z4. If we send … Read more

LTE MIMO Types of Inputs and Outputs

LTE MIMO Types of Inputs and Outputs LTE MIMO “input” and “output” are used for medium between transmitters and receivers, including both RF components – known as the “channel”. Thus, the base station with two transmitters provides two inputs to the channel, “mi” page, and the handset takes two strings get two out of the … Read more

Single User and Multi User MIMO codewords in LTE

Single User and Multi User MIMO codewords in LTE Figure shows how the two codewords are used for a single user in the downlink. It is also possible that the code words to be assigned to different users to create multi-user MIMO (MU-MIMO). Depending on the channel information available in the eNB, modulation and precoding … Read more

Receiver Design for LTE

Receiver Design for LTE The main objective of the study is to take action for the entire measurement receiver. However, many factors can affect the performance of the receiver, such sub-blocks of receipt must be checked on the basis of the first and measurable contributions eliminate or reduce uncertainty. If using multiple receivers, it is … Read more

What is the difference between 4G and 4G LTE?

What is the difference between 4G and 4G LTE? Many people use the terms 4g and 4g interchangeably, but they are not the same. Lets find out the difference…. Features of 4g 4G is the next step above and a 3g replacement, offering faster speeds for users who stream media (such as videos or mp3s), … Read more
