Whether you're working on game development, data visualization, or interactive applications, LiteGraph provides a versatile and powerful platform to bring your ideas to life.

This is not a full tutorial of C++. You won't find lectures here about some very basic syntax: control loops, basic operations etc. Instead, it offers various examples to show the key features of C++ and class related operations.

• class: intro, access specifiers, friendship, constructor, destructor, polymorphism ...
• smart pointers: shared_ptr, unique_ptr, weak_ptr
• template: class template, function template, variable template
• misc: type casting, different pass by types

This website tries to:

• explain 5G New Radio (NR) based on 3GPP specifications, thus, ensures accuracy of the descriptions.
• provide additional explanations when the specification is not easy-to-understand.
• provide interactive examples alongside the specification. It's much easier to learn things with examples, than trying to figure out how it works by yourself.
• provide a set of toolboxes that can be handly for daily work. E.g., frequency/ARFCN/raster converter, OFDM signal generator etc.
• provide a easy way to browse RRC Information Elements.

4G Long Term Evolution (LTE), first commercialized with release 8 in 2008, is a widely used wireless communication system. I don't want to spend time writing tutorial for an "old" technology. Only Radio Resource Control (RRC) messages are provided.
