Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 105 === With the development of wireless communication technology,LTE(Long Term
Evolution) plays an important role in the fourth generation of mobile communication
technology.In this thesis,we introduce for the LTE downlink system,including the use
of OFDM(Orthogonal Frequency Division Multiplexing) technology,specications and
downlink modulation principle,etc.
In this thesis,we used Software-dene-radio to achieve LTE downlink transmitter
and receiver.By the Software-dene-radio platform,we can immediatly transmit
and receive signal in the air on some particular band.Also we can change transmit
and receive gain to observe the transformation of the signal in the air, discussion
on the quality of the signal and system,etc.
