Software Defined Radios (SDRs) have become a fundamental building block for research on wireless networks. Yet, using this platform for experiments in the field is hindered by many practical difficulties, an important one being the need for Automatic Gain Control (AGC). We demonstrate a way of implementing an AGC algorithm directly in the FPGA where we are able to meet tough timing constraints. This...
We present the first steps towards an Open Source simulation and experimentation framework for IEEE 802.11p networks. The framework is implemented based on GNURadio, a real-time signal processing framework for use in Software Defined Radio (SDR) systems. The core of the framework is a modular Orthogonal Frequency Division Multiplexing (OFDM) transceiver, which has been thoroughly evaluated: First,...
