| Summary: | 碩士 === 國立成功大學 === 電機工程學系 === 86 === It is very important to transfer the radio signal well. Direct
Sequence SpreadSpectrum (DSSS) is used as the technology of
modulation. It has manay well-known properties suitable for the
future personal communication, sucj as anti-multipath fading,
low transmission power and compatiability with present narrow-
band systems. The Z2000 Direct Sequence Spread Spectrum
transceiver is adopted as the development platform for wireless
data communications. By selecting the properparameter, we could
reduce the experimental transceiver. Through the personal
computer interface, this spectrum transceiver moduleis supposed
coded voice data 64 kbps. When the lookback self-test is the
trans-ceiver model, this transceiver module could process datas
at 8K byte/sec. In addition, the computers could transmit datas
and files to each other by this transceiver.
