Question | What is Spread Spectrum? |
|
|
|
|
|
|
Answer | Spread Spectrum technology is a wideband radio frequency |
| |
| technique developed by the military for use in reliable, secure, |
| |
|
| ||
| 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 |
| |
| produces a signal that is, in effect, louder and thus easier to |
| |
| detect, provided that the receiver knows the parameters of the |
| |
|
| ||
| tuned to the right frequency, a |
| |
| like background noise. There are two main alternatives, Direct |
| |
| Sequence Spread Spectrum (DSSS) and Frequency Hopping |
| |
| Spread Spectrum (FHSS). |

Question | What is DSSS? What is FHSS? And what | are their |
|
| differences? |
|
|
Answer | 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 |
| |
| 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 |
