| Summary: | 碩士 === 大同工學院 === 電機工程研究所 === 81 === In this thesis we present the simulation methodology and the
prediction of average bit error rateo wireless digital
transmission system in multipath fading channel model. For
considering wiresless digital transmission problem there may be
more than one path from transmitter to receiver. Associated
with each path is a propagation delay and a attenuation
factor. Both the propagation delays and attenuation factors
are time-variant as a result of change in the structure of the
medium. Therefore the characterization of the multipath
channel serves as a model for signal transmission is very
important. We establish multipaht channel models, all these
channel models are described under each constraints and
assumptions. As demand grows for wireless digital
communication systems, the acurate prediction of average bit
error rate for different modulation schemes will become
increasingly important in system design. We present the
methodology and implementation of average BER simulation and a
step-by-step approach is used to verify the basic ideal and
channel models.
