Sensing in autonomous vehicles is a growing field due to a wide array of military and reconnaissance applications. The Adaptive COMMUNICATIONS and Signals Processing Group (ACSP) research group at Cornell specializes in studying various aspects of autonomous vehicle control. Previously, ACSP has examined video sensing for autonomous control. Our goal is to build on their previous research to incorporate audio source tracking for autonomous control.
This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The
file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to
"capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2.
All programs are verified with MATLAB versions 6.0 and above with signal processing and COMMUNICATIONS toolboxes.
The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,
and MAX1487E are low-power transceivers for RS-485 and
RS-422 COMMUNICATIONS in harsh environments. Each driver
output and receiver input is protected against ±15kV electrostatic
discharge (ESD) shocks, without latchup. These parts
contain one driver and one receiver. The MAX483E,
MAX487E, MAX488E, and MAX489E feature reduced slewrate
drivers that minimize EMI and reduce reflections caused
by improperly terminated cables, thus allowing error-free
data transmission up to 250kbps. The driver slew rates of the
MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E
are not limited, allowing them to transmit up to 2.5Mbps.
After the successful global introduction during the past decade of the second generation (2G) digital
mobile COMMUNICATIONS systems, it seems that the third generation (3G) Universal Mobile Communication
System (UMTS) has finally taken off, at least in some regions. The plethora of new services that
are expected to be offered by this system requires the development of new paradigms in the way scarce
radio resources should be managed. The Quality of Service (QoS) concept, which introduces in a natural
way the service differentiation and the possibility of adapting the resource consumption to the specific
service requirements, will open the door for the provision of advanced wireless services to the mass
market.
Ultra wideband (UWB) technology, well-known for its use in ground penetrating
radar, has also been of considerable interest in COMMUNICATIONS and radar applications
demanding low probability of intercept and detection (LPI/D), multipath immunity, high
data throughput, precision ranging and localization.
It has been suggested1 that an appropriate figure of merit for a low probability of intercept and
detection (LPI/D) waveform is the quantity “Range x Bandwidth / Joule”. That is, the further the
range, the wider the bandwidth and the less amount of energy used to achieve these values, the
more covert is the resultant COMMUNICATIONS system.

HsGpsDll Library 1.1
A GPS Control/Component for C/C++
HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial COMMUNICATIONS port. HsGpsDll is designed for use from Visual C, Visual Basic or other languages, capable of calling DLL functions. HsGpsDll allows a user application to read from a GPS device the current GPS position fix, velocity over ground (speed in kilometers per hour), plus number of of sattelites in view, current altitude (against mean sea level) and UTC date and time
