Advantages, disadvantages and applications of direct sequence spread spectrum (DSSS)

Advantages:

There are some advantages of direct sequence spread spectrum which are given below,

• It has best discrimination against multipath signals.
• It avoids intentional interference such as jamming effectively.
• Performance of DSSS system in presence of noise is better than FHSS system.

Disadvantages:

There are some disadvantages of direct sequence spread spectrum which are given below,

• This system becomes slow due to large acquisition time.
• It requires wideband channel with small phase distortion.
• The pseudo noise generator should generate sequence at high rates.

Applications:

There are some applications of direct sequence spread spectrum which are given below,

• It is used in the low probability of intercept signal.
• It is used in military and many commercial applications.
• Code division multiple access with direct sequence spread spectrum.
