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 … Continue reading →

MIMO System Prototyping Prototyping is key to understanding the operation of real-world wireless systems. It provides access to real propagation channels and better simulations impairments such as amplifier nonlinear, gain/phase offset, quantization effects, and timing jitter that are often overlooked in simulations. To obtain the benefits from studying these effects, we have built several prototypes to study topics such as MIMO-OFDM communication and MIMO ad hoc networking. Click on the … Continue reading →
