GEDOMIS testbed (part 1)

GEDOMIS testbed (part 1)GEDOMIS® (GEneric hardware DemOnstrator for MIMO Systems) is a multi-antenna wireless communication testbed that enables the prototyping and evaluation of physical layer algorithms featuring MIMO techniques. This is feasible thanks to its heterogeneous and reconfigurable structure comprising mixed FPGA and DSP baseband signal processing components, which can be used for the implementation and real-time validation of broadband wireless communication systems. GEDOMIS® is currently hosting an IEEE 802.16e-2005 system (mobile WiMAX) featuring a 2×2 MIMO configuration with a high channel bandwidth of 20 MHz. The physical layer algorithms of the receiver were modeled in Matlab, designed in VHDL and implemented in a real-time FPGA platform from Lyrtech Inc. For more information visit our webpag Source

Linux Embedded RTL-SDR Receiver

Janos over at embrtlsdr has a new post regarding his work making a Linux powered SDR using RTL based dongles and Ethernet.

“The basic idea was to run the small rtl-sdr util on a small embedded box connected with the dbv-t dongle at near the antenna, and transmit the data on ethernet connection. The more processing and vizualization can be continue on the desktop/laptop machines.
To this setup I choosed my old small linux box, the NSLU2. It has 2 USB conncetors, network connection, and, more than 2 years ago I installed on it a Debian lenny version, on a 4 Gbyte pendrive.”
