Abstract

The half-duplex (HD) technology, which is utilized as a communication method in contemporary wireless internet, is being questioned due to its inability to achieve desired data rates in response to the growing demand. The full-duplex (FD) technology which is one of the recommended technologies for 5G advanced, meets this demand by utilizing the channel more efficiently and increasing data rates by enabling simultaneous transmission (Tx) and reception (Rx) at the same frequency. In both academic and industrial domains, various studies are being conducted and continue to explore the adaptation of FD technology to Wi-Fi. One of these proposed medium access control (MAC) protocols is the Synchronized Contention Window Full-Duplex (S-CW FD) protocol. In this thesis, the building blocks of the S-CW FD protocol, which has previously been shown to increase throughput by 1.5–2 times in simulation, are implemented on the wireless open-access research platform (WARP) field-programmable gate arrays (FPGA): the packet header is modified according to the protocol, the two nodes are synchronized to enable simultaneous transmission, and a digital self-interference cancellation (SIC) module is developed. The design is then migrated to a portable, hardware-agnostic Register-Transfer Level (RTL) architecture, and the throughput gain of the protocol is evaluated in a simulation environment under the assumption of ideal self-interference cancellation.
