Putting the Software Radio on a Low-Calorie Diet

Free registration required

Executive Summary

Modern software-defined radios are large, expensive, and power-hungry devices and this, the authors argue, hampers their more widespread deployment and use, particularly in low-power, size-constrained application settings like mobile phones and sensor networks. To rectify this problem, they propose to put the software-defined radio on a diet by redesigning it around just two core chips - an integrated RF transceiver and a Flash-based, mixed-signal FPGA. Modern transceivers integrate almost all RF front-end functions while emerging FPGAs integrate nearly all of required signal conditioning and processing functions.
