Prototyping

Prototyping

Implementation is key to understanding the operation of real-world wireless systems. At the physical layer, prototyping provides access to real propagation channels. It also exposes the system designer to impairments such as amplifier nonlinear, gain/phase offset, quantization effects, and timing jitter, which are often overlooked in simulations. At the MAC layer, prototyping can be used to explore the benefits of advanced transceiver architectures like MIMO-OFDM, interference cancelation, and  adaptive transmission techniques. Many network simulators do not have enough physical layer fidelity to incorporate physical layer tradeoffs. At higher layers, prototyping can be used to show how technical achievements at the lower layers impact end-to-end performance objectives.

In the past ten years, we have been involved with several different prototyping activities. Our most recent work includes developing joint framework for radar and communications at both the microwave and millimeter wave bands. Our prototypes over the years have involved a variety of different hardware platforms including the GNU radio Ettus boards, National Instruments radio frequency hardware, and Texas Instruments development kits.
