WebDirect sequence spread spectrum (DSSS) transmission employs a chipping code to “spread” the transmission over a wider frequency band than it would normally occupy. DSSS is a form of CDMA (see Chapter 4 ). But instead of a pseudorandom binary sequence (PRBS), an 11-bit Barker code is used as the spreading sequence.
