This program shows the distributions of the co-channel interference in forward and reverse link in the cellular mobile system with cluster size N, when the mobile subscriber (MS) is at random positions of a cell.
NAME Control_AT24Cxx
This collection of routines allows an AT89C2051 microcontroller to read
and write the AT24Cxx family of serial CMOS EEPROMS. This version of the
code is compatible only with the AT89C2051 due to the location of the
data buffer and stack in RAM. The code may be modified to work with the
AT89C1051 by relocating or resizing the buffer and stack to fit into the
smaller amount of RAM available in the AT89C1051. Note that the minimum
size of the buffer is determined by the page size of the AT24Cxx.
This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems. The first three editions of Programming the Finite Element Method established themselves as an authority in this area. This fully revised 4th edition includes completely rewritten programmes with a unique description and list of parallel versions of programmes in Fortran 90. The Fortran programmes and subroutines described in the text will be made available on the Internet via anonymous ftp, further adding to the value of this title.
The first task at hand is to set up the endpoints appropriately for this example. The following code switches the CPU clock speed
to 48 MHz (since at power-on default it is 12 MHz), and sets up EP2 as a Bulk OUT endpoint, 4x buffered of size 512, and EP6
as a Bulk IN endpoint, also 4x buffered of size 512. This set-up utilizes the maximum allotted 4-KB FIFO space. It also sets up
the FIFOs for manual mode, word-wide operation, and goes through a FIFO reset and arming sequence to ensure that they are
ready for data operations
This project aim was to build wireless software modem for data communication
between two computers using an acoustic interface in the voice frequency range (20Hz–
20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz –
20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz –
16,000Hz). The test files used as information files were text files.
This goal was attained both in an incoherent scheme and in a coherent scheme.
Build under Matlab code, our modem uses OFDM (orthogonal frequency division
multiplexing) modulation, synchronization by LMS sequence, channel estimation (no
equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of
2 or 4. To optimize the probability of error, these symbols were mapped using Gray
mapping.
Report
The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabilities.
The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the system’s
processor bus, providing faster data transfers
between the processor and peripherals. The PCI Local
bus also addresses the industry’s need for a bus standard
which is not directly dependent on the speed,
size and type of system processor. It represents the
first microprocessor independent bus offering performance
more than adequate for the most demanding
applications such as full-motion video.

These functions are provided to help you develop your initial code.
They are optimized for speed rather that size. As a result, you will
see very few nested function calls. If speed is not critical, you
can use function calls for common tasks (like dat polling after
writing a byte to Flash) The penalty is the extra processor
time to make the nested calls.
三維矢量有限元-矩量法電磁場分析程序。
EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.
