System for continuous wave rejection |
摘要 |
A method for receiving transmitted signals in the presence of CW interference is used in a communication system that determines the presence of a code in a received signal. A detector threshold is compared calculations made in accordance with a sample of a received signal. A first input power value of the received signal is obtained at a first sample time and a second input power value of the received signal is obtained at a second sample time. The first and second power values are compared in order to provide an input sample comparison and the forgoing steps are repeated in order to provide a plurality of input sample comparisons, and the detector threshold is adjusted in accordance with the plurality of sample comparisons. The CW signal can be strongly correlated with a short code used for the acquisition purposes, while avoiding false alarms.
