| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 81 === Spread-Spectrum (SS) wireless local network applies the
techinque of SS communication to transmit data. The method of
its transmission first is to mix both signal and chip code,
then to use PSK to transmit. Local area network using SS to
transmit have a lot differentiation with general wireless or
wire network such as the method of transmission and receipt 、
decoding techinque and the problem of code synchronous. Those
problems all must be considered in the subject of searching SS
network properties. The thesis search how to get improving in
the performance of network when use SS techinque in ALOHA and
CSMA protocols. Under SS transmission, because the time that
receiver spent to capture the PN code of transmitter is not
fixed ,so it will maybe make quit large variation in the
performance of network. Hence, we will use different capture
time to analy network for getting practice result and to
compare with traditional network. Finally, we hope that we can
get suitable the technique and protocol of SS local area
network.
