What is DSSS BPSK?

Direct Sequence Spread Spectrum (DSSS) using BPSK modulation, so the first reversing switch introduces 180 degree phase reversals according to a pseudo-random code, while the second introduces the same reversals to reconstitute the original, narrow-band signal. The output is a “recompressed” narrow-band signal.

What is the spreading factor in DSSS?

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.

Can we share a bandwidth in DSSS?

Not spectrally efficient for one user, but DSSS also allows many users to share the same bandwidth (MAC technique).

What is the importance of spreading gain in DSSS?

The primary benefit of processing gain is its contribution towards jamming resistance to the DSSS signal. The PN code spreads the transmitted signal in bandwidth and it makes it less susceptible to narrowband interference within the spread BW.
