Abstract
The advent of software radio technology has enabled radio developers to design and imple-

ment radios with great ease and flexibility. Software radios are effective in experimentation

and development of radio designs. However, they have limitations when it comes to high-

speed, high-throughput designs. This limitation can be overcome by introducing a hardware

element to the software radio platform. Enhancing GNU Radio for Hardware Accelerated

Radio Design project implements such a scheme by augmenting an FPGA co-processor to

a conventional GNU Radio flow. In this thesis, this novel platform is evaluated in terms of

performance of a radio design, as well as hardware and software system requirements. A

simple and efficient Zigbee receiver design is presented. Implementation of this receiver is

used as a proof-of-concept for the effectiveness and design methodology of the modified GNU

Radio. This work also proposes a scheme to extend this idea for design of ultra-wideband

radio systems based on multiband-OFDM.
