To fully utilize the available spectrum for a wireless communication
system it is feasible to adapt to different situations
on the channel. In this paper a flexible OFDM
transmitter is presented together with basic theory behind
OFDM transmission. It is shown that high flexibility can
be obtained with a reasonable amount
Flexible baseband transmitter for OFDM
of additional hardware.
Part of the design, the FFT-processor, has already
been fabricated and measurement results are presented.

Windows CE Embedded CE 6.0 driver installation.
1. Unzip the installation file onto your system (called installation directory below)
2. Create an OS design or open an existing OS design in Platform Builder 6.0.
a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items).
b. Run image size should be set to allow greater than 32MB.
3. a. From the Project menu select Add Existing Subproject...
b. select AR6K_DRV.pbxml
c. select open
This should create a subproject within your OS Design project for the AR6K_DRV driver.
4. Build the solution.

RFID data transmission design model with news transmission mechanism，for realizing data transmission more effectively，
RFID data transmission design model with news transmission mechanism，for realizing data transmission more effectively，
The design of control systems involving piezoelectric actuators and sensors requires an accurate knowledge of the transfer functions between the inputs and the outputs of the system.
The goal of our final project was to design an efficient elevator simulator that can accept input from a user and mechanically operate (on a small scale) a system of 4 floors and 3 elevators using pulleys and stepper motors. Users enter input using physical pushbuttons or the computer. This input is then processed by the MCU and orders are given to the elevators. We attempted to devise an algorithm that can optimally handle any number of floors. This project seemed like a fun challenge and something that had practical applications. Both of us have been frustrated at times by the inefficiency of some of the elevators here at Cornell, and we wanted to see if we could do a better job.

The system uses ADO data access technology, and each database table and operation of the field to the type of package, which succeeded in object-oriented programming thinking applied to the database application design.
This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System. As a first release it s still rather rough and very much larger than desired however it is working well in an embedded product and therefore may be useful to others. Much of the code is ported from public sources including BDS Lite and KA9Q (and its derivatives) and carries copyright notices from those sources. Essentially TCP is based on KA9Q but with ideas from BSD, IP is a simple implementation supporting BSD structures, ICMP is ported from BSD, and PPP is ported from the BSD version of the distribution common to BSD, Linux, and many other systems
Learn how to build a custom Linux® distribution to use in an embedded environment,
in this case to drive a Technologic Systems TS-7800 single-board computer. In this
tutorial, you learn about cross-compiling, the boot loader, file systems, the root file
system, disk images, and the boot process, all with respect to the decisions you
make as you re building the system and creating the distribution.
