Abstract
A communication system comprises direct sequence spread-spectrum demodulator that receives first and second signals and that correlates a spreading code with a preamble of each data packet to produce a spreading codeword including a predetermined number of chips. A signal quality measurement device is responsive to the direct sequence spread-spectrum demodulator, measures signal quality values corresponding to each of the first and second signals for each data packet after correlation with the spreading code and that selects one of the first and second signals on the basis of the measured signal quality values.
