X-MAC, a low power MAC
protocol for wireless sensor networks (WSNs). Standard
MAC protocols developed for duty-cycled WSNs such as
BMAC, which is the default MAC protocol for TinyOS, employ
an extended preamble and preamble sampling.
We present a particle filter construction for a system that exhibits
time-scale separation. The separation of time-scales allows two simplifications
that we exploit: i) The use of the averaging principle for the
dimensional reduction of the system needed to solve for each particle
and ii) the factorization of the transition probability which allows the
Rao-Blackwellization of the filtering step. Both simplifications can be
implemented using the coarse projective integration framework. The
resulting particle filter is faster and has smaller variance than the particle
filter based on the original system. The convergence of the new
particle filter to the analytical filter for the original system is proved
and some numerical results are provided.
YSS915 (KP2V2) is an LSI for processing Karaoke voice signals.
This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and
key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI
chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that
YSS915 is applicable to various uses.
In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the
surround effect is applied to the movie and music sources for giving the users more enjoyment.
YSS915 is pin compatible with and register compatible with YSS903 (KP2V).
The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding
by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been
implemented for a 2x2 system. The reader can program other variations.
The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
This is the Low Energy Adaptive Clustering Hierarchy routing protocol [LEACH] source code for wireless sensor network we have used.It is developed with MatLab7
