PPT-SPREAD SPECTRUM In spread spectrum (SS), we

spread a signal over a wide bandwidth larger than BW in traditional communication systems These techniques are used for a variety of reasons including the establishment of secure communications increasing resistance to natural interference noise and jamming. spreadorg Spread provides a range of reliability ordering and stability guarantees for message delivery Spread supports a rich fault model that includes process crashes and recoveries and network partitions and merges under the extended virtual sync 381a and b brPage 4br mt Fig 7381 b Direct sequence spread spectrum receiver Fig7381 b Binary Adder Balanced Modulator Pseudo noise code enerator Transmitted signal st ct Carrier Frequency f Fig 7381 a Direct sequence spread spectrum transmitter mt Examine external and internal factors that affect spread.
