SPREAD SPECTRUM FREQUENCY HOPPING SYSTEM AND METHOD

摘要

A frequency hopping spread spectrum wireless transmission system includes a transmitter (10) and a receiver (38) system. The transmitter (10) is configured to transmit radio frequency data signals in sequential time periods on respective transmit channels according to a predetermined sequence. The data signal in each time period includes information relating the data signal to its position within the predetermined sequence. The receiver (38) system is configured to monitor a plurality of receive channels over a frequency range that includes the transmit channels and to receive the data signals on the receive channels. The receiver (38) system is also configured to determine, upon reception of a first data signal on a first receive channel, a next receive channel based on the first receive channel so that the next receive channel differs from the first receive channel an amount equal to the interval between the data signals position and the next position in the sequence, and to monitor the next receive channel for a next data signal.
