September WCA Meeting Agenda:

"Challenges and Solutions in Broadband Communication Systems
Verification" Jack Anderson, Founder and CTO of Celerity Systems
Inc, an L-3 Communications Company

Today's generation of broadband communications has pushed the "state
of the art" to new levels, with faster data rates, more sophisticated
modulation schemes, and highly complex coding algorithms. These new
signal structures have increased sensitive to impairments such as
thermal noise, I/Q imbalance, phase noise, phase/amplitude distortion,
channel loading, multipath, and interference. It is important to
test and characterize new designs with signal environments that can
closely emulate the real world. Likewise, engineers must have tools
that allow them to interpret the effects of the signal impairments.

In this talk, Celerity will discuss these real world impairments
through examples that illustrate their effects on system performance.


GNU Radio- An introduction and overview of Software Defined Radios
(SDR) based on the GNU Software model Steve Schear, CEO of Lamarr
Labs.

GNU Radio is a collection of open source software (based on the GNU
model) that when combined with minimal hardware, allows the
construction of radios where the actual wave forms transmitted and
received are defined by software. What this means is that it turns
the digital modulation schemes used in today's high performance
wireless devices into software problems. On the receive side, the
idea is to get a wide band analog-to-digital converter as close to
the antenna as is convenient, get the samples into the PC's memory
and then grind on them in software.

The talk will include an over view of SDR, its advantages and
disadvantages, how SDR fits into current and emerging applications,
the current direction of GNU Radio, and some of the regulatory/political
implications of open SDR.


WCA is a nonprofit corporation dedicated to the mutual benefit of
Northern California companies and organizations involved in wireless
communication technologies.

  "A mass in movement resists change of direction. So does the world
  oppose a new idea. It takes time to make up the minds to its value
  and importance. Ignorance, prejudice and inertia of the old retard
  its early progress. It is discredited by insincere exponents and
  selfish exploiters. It is attacked and condemned by its enemies.
  Eventually, though, all barriers are thrown down, and it spreads
  like fire. This will also prove true of the wireless art." 
  - Nikola Tesla in 1908
