Design of Rate-Compatible Protograph LDPC Codes
The most common way to generate a rate-compatible family of codes is puncturing. In this method, one starts with a low-rate mother code and then selectively discards some of the coded bits to arrive at higher-rate codes. This approach is simple, but is not free of problems. Specifically, the mother...

Ionospheric Slant TEC Analysis Using GNSS-Based Estimation (IonoSTAGE)
As signals emitted by global navigation satellite systems (GNSS) propagate toward users on or near the surface of the Earth, they experience delay due to the presence of charged particles in the ionosphere. Currently, ionospheric delay is the largest source of GNSS positioning...
