UEBERTRAGUNGSSYSTEM MIT GESPREITZTEM SPEKTRUM. |
摘要 |
Disclosed is a spread spectrum communication system realized by using the frequency hopping coherent detection system wherein such an offset voltage pattern is predetermined by a polynomial is applied to the VCO of the PLL in the receiver thereof, so that the PLL can be operated with a narrow bandwidth because of the narrow bandwidth of the loop filter as well as a decreased loop gain while avoiding tracking break caused by narrow lock range due to the narrow bandwidth of the loop filter as well as the decreased loop gain. |
