Hello Everyone,
With great pride, we say to world that for better
research on SDR,we have decided to release all the *SCHEMATICS*,
*GERBER *files,
*PCB *files. With these files, any one with decent knowledge in hardware
domain can build a 2x2 mimo full duplex sdr on his/her own. This is
gnuradio 2x2 mimo full duplex sdr. The files uploaded are original design
files and they are working as a product. A brief explanation on its
capabilities

you will find *ASRP1 assembly files, Bill of Materials, Board Schematics,
Gerber files* of the same. Happy sdr to world.
Full Duplex Software Defined Radio compatible with GNU Radio + allowing the
user flexibility in changing their radio through software.
A software radio is a wireless communications device that performs all of
its signal processing in portable, application level software. By simply
running a different program, a software radio can become a cell phone,
wireless LAN, cordless phones, garage door opener or walkie-talkie. The
flexibility enabled by software radio allows for faster technology
tracking, since standards upgrade are simple software downloads. Software
radio is a multi-disciplinary systems effort, bringing together research in
digital signal processing, communications, operating systems, software
engineering and algorithms.
ASRP MIMO is a daughtercardless 2x2 full duplex SDR transceiver complete
with RF and DAQ subsystems on a single board.
In radio <https://en.wikipedia.org/wiki/Radio>, M*ultiple-Input and
Multiple-Output*, or *MIMO* (commonly pronounced my-moh or me-moh), is the
use of multiple antennas at both the transmitter and receiver to improve
communication performance. It is one of several forms of smart
antenna<https://en.wikipedia.org/wiki/Smart_antenna>
technology.
Its architecture is designed for a true MIMO System. It meets the unique
architecture required for MIMO systems which are not part of traditional
MIMO hardware using common clock for RF subsystems where a continuous RF
phase tracking is required. Coupled with these benefits, it hosts onboard
RF transceiver subsystems capable of tuning frequencies from 400MHz to
4.4GHz.
*Supports: Windows / Linux

*SOFTWARE*
*AndroidSDRv1001* is a LiveDVD/USB image to support this SDR device without
configuration nightmares and when connected to appropriate SDR hardware,
allows for the creation of "Software Defined Radio GSM Mobile Phone
Networks", for example.
This includes Android Studio 0.1.1 Build 130.687321 Environment, as well as
contains:
*Asterisk 1.8 *http://www.asterisk.org/
*GCC 4.6.3 *gcc.gnu.org/ <http://gcc.gnu.org/%E2%80%8E>
*GNU Radio 3.4.2 + GRC *http://www/gnuradio.org/
*Java 1.7.0_21 *www.java.com/ <http://www.java.com/%E2%80%8E>
*OpenBTS 2.8 *www.openbts.org/
*Ubuntu 12.04 LTS 32-bit *http://releases.*ubuntu*.com/precise/
*Pre-configured to work with Google Voice: just add your Google Voice Email
Address & Password. *https://www.google.com/voice
You should be able to boot off the LiveDVD / USB image and create an SDR
GSM Network in under 10 minutes cleanly.
***UHD Driver needs to be implemented to get the GNU Radio versions 3.4.2
through 3.7 applications to function****
*If you are within the USA , Part 15 of the FCC Rules & Regulations allows
for utilizing SDR devices as Test Equipment. Ettus Research, PerVices, &
other Software Defined Radio providers sell their products under the
following (Generally Speaking):*
