Pulse shaping and spectrum in LTE
RF engineering is a trade off between: required radio spectrum (bandwidth), speed of data transmission (bit rates) and complexity of implementation. The pulse form used to modulate complex data symbols…

Here we discus about LTE Technology, detail on 4G and How to LTE.
Types of Handover in LTE
The Handover is the process of transferring an ongoing call or data session fromone cell connected to the core network to another It is transparent for the end user It…
Which Cell Parameters needs to Obtain in LTE?
To provide the most critical information to the UEs, the eNodeB uses the BCH channel The information is sent on pre-defined time-frequency resources. This information is organized into different information…
Modulation in LTE
The 3G LTE uses 3 Quadrature Amplitude Modulations (QAMs) depending on the radio quality. QAM uses both the amplitude and the phase. LTE devices use QPSK, 16QAM and 64QAM to…
LTE Sub-carrier
How Many Sub Carrier in LTE? Read below,..There are different kinds of sub-carriers: Data sub-carrier Pilot Sub-carrier DC sub-carrier Guard Sub-carrier The result is intersymbol interference not only within a…
MIMO Principles
MIMO is effectively radio antenna technology because multiple antennas are used at the transmitter and receiver to allow a variety of signal paths to transmit the data, with separate paths…
Handover Process in LTE
The source eNB issues a HANDOVER REQUEST message to the target eNB passing the necessary information to prepare the HO on target side (UE X2 signaling context reference at source…
What is EPS Bearer in LTE?
Eps bearer LTE EPS is a connection-oriented transmission network and, as such, it requires the establishment of a “virtual” connection between two endpoints (e.g. a UE and a PDN-GW) This…
How Downlink Control Information or DCI in LTE?
Downlink Control Information or DCI in LTE The PDCCH carries Downlink Control Information or DCI to indicate the resource assignment in UL or DL for one RNTI. A DCI can…
Packet Data Convergence Protocol (PDCP) in LTE
What is pdcp in lte: – PDCP means Packet Data Convergence Protocol means it convert data at protocol level let’s check its function at user plane and control plane in details….
Timing Advance in LTE
Timing advance lte what is timing advance in lte: -The eNB measures the required timing advance based on the received UE signal arrival time. It commands the UE to adjust…
Resource Block & Physical Resource Block in LTE
What is Resource block in lte? :- A resource block is the smallest unit of resources which allocated to a user. The resource block is 1 slot long in time…
