Detailed explanation-1: -DSSS system spreads the baseband signal by the baseband pulses with a pseudo noise sequence. Explanation: A direct sequence spread spectrum (DS-SS) system spreads the baseband data by directly multiplying the baseband data pulses with a pseudo noise sequence.

Detailed explanation-2: -One of the most essential attributes of DSSS coding is the spreading factor, which is defined as the quotient of the chip rate and the bit rate. As suggested by the above characteristics, DSSS does not affect the transmission time for the same transmitted packet.

Detailed explanation-3: -Direct 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.

Detailed explanation-4: -In telecommunications, direct-sequence spread spectrum (DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth.
