16. e What is Spread Spectrum Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable secure mission critical communications systems It is designed to trade off bandwidth efficiency for reliability integrity and security In other words more bandwidth is consumed than in the case of narrowband transmission but the trade off produces a signal that is in effect louder and thus easier to detect provided that the receiver knows the parameters of the spread spectrum signal being broadcast If a receiver is not tuned to the right frequency a spread spectrum signal looks like background noise There are two main alternatives Direct Sequence Spread Spectrum DSSS and Frequency Hopping Spread Spectrum FHSS What is DSSS What is FHSS And what are their differences Frequency Hopping Spread Spectrum FHSS uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver Properly synchronized the net effect is to maintain a single logical channel To an unintended receiver FHSS appears to be short duration impulse noise Direct Sequence Spread Spectrum DSSS generates a redundant bit pattern for each bit to be transmitted This bit pattern is called a chip or chipping code The longer the chip the greater the probability that the original data can be recovered Even if one or more bits in the chip are damaged during transmission statistical techn
