ABSTRACT:
A transceiver for transmitting and receiving spread spectrum signals having an adaptive threshold for distinguishing between valid receive data signals and noise. The transceiver includes a transmitter for transmitting spread spectrum signals and a receiver for receiving spread spectrum signals. A correlator correlates a received signal against an expected receive pattern. The correlation of the received signal is compared to a threshold value. If the correlation exceeds the threshold value, a carrier detect signal is generated. The number of false carrier detect signals occurring within a pre-determined period of time is determined. The threshold value is varied according to the number of false carrier detects.
