| Summary: | 碩士 === 國立中央大學 === 通訊工程研究所 === 99 === Because wireless signals in the channel through the external environment, often will be some phase error, or objects moving in Governor frequency offset caused by Doppler effect, etc., may also be sent to sub-carrier frequency itself has errors, these errors will become difficult to decode the real signal reconstruction.
In this study, using real-LTE (Long Term Evolution) of PDSCH (Physical Downlink Shared Channel) signal is recorded as a digital file, then C + + programming software decoding, using the CP to do the CFO compensation, and LTE specifications in the PSS (the main coherent signal) of ZC (Zadoff-Chu) sequences to do the correct frequency and phase coherent. Implementation process is based on MATLAB software simulation ZC sequence of the various properties, and then use the C + + solution of the real signal is stored as digital files.
