تعريف dsss في الإنجليزية الإنجليزية القاموس.
- Direct Sequence Spread Spectrum One of two modulation schemes prescribed by the IEEE 802 11 standard group for wireless transmission, and the transmission method employed by IEEE 802 11b DSSS combines the data signal with a higher data rate bit sequence, called a chipping code, to improve noise resistance and data integrity
- Direct Sequence Spread Spectrum DSSS modulates frequency using a predefined "spreading code" algorithm DSSS jumps much faster than Frequency-Hopping Spread Spectrum (FHSS)
- Direct Sequence Spread Spectrum A spread spectrum modulation that divides the 2 4 GHz band (83 MHz wide) into three 24 MHz channels One wireless LAN uses one channel Each bit of data fills the channel with multiple frequencies More complex than Frequency Hopping, but semiconductor improvements have reduced the cost
- Direct Sequence Spread Spectrum One of the two major classes of RF modulation used in spread spectrum communications
- Direct Sequence Spread Spectrum
- Direct sequence spread spectrum A type of spread spectrum radio transmission that spreads its signal continuously over a wide frequency band
- Acronym for Direct-Sequence Spread Spectrum DSSS is a transmission technology used in WLAN (wireless LAN) transmissions where a data signal at the sending station is combined with a higher data rate bit sequence, or chipping code, that divides the user data according to a spreading ratio The chipping code is a redundant bit pattern for each bit that is transmitted, which increases the signal's resistance to interference If one or more bits in the pattern are damaged during transmission, the original data can be recovered due to the redundancy of the transmission
- Direct Sequence/Spread Spectrum
- Direct Sequence Spread Spectrum - a transmission technology in which a data signal at the sending station is combined with a higher data rate bit sequence, or chipping code, that divides the user data according to a spreading ratio The chipping code is a redundant bit pattern for each bit that is transmitted, which increases the signal's resistance to interference If one or more bits in the pattern are damaged during transmission, the original data can be recovered due to the redundancy of the transmission
