| dc.description.abstract | 本論文在介紹有關Chirp 線性調頻脈衝，因為線性調頻脈衝信號具有
的各種優點，很適合無線的通訊環境，在有限的發送功率下，要送到更遠
的地方，需要較大的頻寬， Chirp Signal 有良好的自相關特性，可以有效降低都普勒效應的影響，所以將線性調變(LFM)實現在硬體上，並與二位元頻率偏移調變(BFSK)的效能做分析與探討。
此外，在平台使用了FPGA 實驗版上做硬體模擬實現，傳送頻帶為

| dc.description.abstract | This thesis presents the chirp communications. Because chirp signal has var-
ious merits which are suitable for wireless communications environment.It can be
transmitted at a greater distance without the need to increase the power of trans-
mitter.Whether it uses the bandwidth much greater than the bandwidth of the data.
For the Doppler shift, chirp signal has the merit to combat Doppler shift because
of the characteristic of its good auto correlation function.We achieved the LFM on the hardware, and compared the ecacy with BFSK.
Otherwise, we used the FPGA to simulate the hardware. The transmission bandwidth is | en_US |
