Title: System for continuous wave rejection
IPC: H04B1/707
Filed: 2000-02-04
Abstract: A method is disclosed for receiving transmitted signals in the presence of CW interference in a communication system that determines the presence of a code in a received signal by comparing with a detector threshold calculations made in accordance with a sample of a received signal. Such systems include but are not limited to those incorporating a Sequential Probability Ratio Test. The method includes obtaining a first input power value of the received signal at a first sample time and obtaining a second input power value of the received signal 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. 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. Therefore in the CDMA systems if the received signal contains a CW signal, then the strong correlation between the CW signal and the short code used for acquisition may result in a false alarm. To prevent this, the following algorithm is suggested to be used for the cancellation of CW, if there is a CW signal present in the received CDMA signal.
