OFDM implementation in Detail

A typical OFDM transmitter is shown on the following figure. To reduce the amount of RF hardware required for OFDM the modulation process is split into two parts. A first

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

What is AMC & its Algorithm in LTE

The effective Eb/No and hence the spectral efficiency depend on BLER. However there are QoS requirements which also have to be considered. Taking both into account leads to a target

What is Smart Antennas in LTE

What is smart antenna? Smart antennas are antenna arrays with intelligent signal processing algorithms that identify spatial signal signatures, such as the direction of arrival of the signal, and calculate the

What is MNC and MCC for GSM

Spread Spectrum Concept

Dsss – Direct sequence spread spectrum DSSS – Direct Sequence Spread Spectrum is a spread spectrum technology in which original data is expand using PN code randomly to reduce noise

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

Difference Between OFDM and FDM in LTE

FDM in LTE Conventional multi-carrier operation as it is used for FDM works simply by selecting a number of center frequencies – one for each carrier to be used. The

What is HLR and VLR and its function in GSM

As From the Name VLR means Visitor Location Register and HLR means Home Location Register so it has all detail of subscriber so VLR has temporary details. Let’s check in
