What is directivity in a coupler ?

Directional couplers are four-port circuits where a defined amount of the electromagnetic power fed at the input port in a transmission line is coupled to a port (known as coupled […]

5G NR Control Plane Latency

The latency performance of a communication system is analyzed for both control plane and user plane. In this post lets discuss about control plane latency. The definition of control plane […]

What parameters impact the EVM of transmitter chain ?

The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation […]

Robust Header Compression – ROHC

ROHC is a header compression protocol/algorithm that can be used compress the header of different IP packets. In normal case without compression  IPv4 header is 40 bytes and IPv6 header […]

TTI Bundling for better HARQ and Latency

TTI bundling enables a data block to be transmitted in consecutive TTIs, which are packed together and treated as the same resource during the scheduling process. TTI bundling makes use […]
