How are bits transmitted using DSSS?
DSSS technology breaks down the transmitted stream of data into small pieces across a frequency channel. A redundant bit pattern (known as a chipping code) is generated for each bit transmitted. Generally, the longer the chipping code, the more likely it is that the original transmitted data will be properly received.
What is a spread spectrum technique explain in detail DSSS?
Spread Spectrum refers to a system originally developed for military applications, to provide secure communications by spreading the signal over a large frequency band. Figure 1 represents a narrow band signal in the frequency domain. These narrowband signals are easily jammed by any other signal in the same band.
What is direct sequence spread spectrum explain with an example?
Direct sequence spread spectrum (DSSS) is a transmission technology used in local area wireless network transmissions. In this technology, a data signal at the sending station is combined with a high data rate bit sequence, which divides user data based on a spreading ratio.
How does DSSS achieve bandwidth spreading?
Direct Sequence Spread Spectrum (DSSS)
DSSS accomplishes its frequency spreading by transforming each bit into a distinct, longer sequence. For example, a single '1' bit might become a particular 11-bit sequence (00010011100).
