Intelligent Reflecting Surfaces to Achieve the Full-Duplex Wireless Communication

IEEE Communications Letters, 2020
The full-duplex (FD) radio-frequency wireless communication theoretically doubles the data rates compared to the half-duplex counterpart. However, its performance depends critically on the self-interference (SI) that exists between transmit and receive ...

Wireless communications fundamentals

2013
Communication stack For convenience in design, the operations of radios are often broken into a number of functional layers. The standard version of this stack is referred to as the open systems interconnection (OSI) model [291], as seen in Figure 4.1. The model has two groups of layers: host and media.
