Abstract
A communication system for communicating data packets includes a receiver subsystem. The receiver subsystem comprises a first antenna, and a second antenna. A direct sequence spread-spectrum demodulator communicates with the first and second antennas. The demodulator is configured to correlate a spreading code with a preamble of each data packet to produce a spreading codeword. The spreading code includes a predetermined number of chips. A signal quality measurement device is responsive to the direct sequence spread-spectrum demodulator. The device is configured to measure signal quality values corresponding to each of the first and second antennas for each data packet after correlation with the spreading code and to select one of said first and second antennas on the basis of the measured signal quality values.
