In telecommunications, direct-sequence spread spectrum (DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation in the receiver, the information ba… WebApr 20, 2006 · DSSS:- Direct Sequence Spread Spectrum. In this , the user does not change the frequency but it changes the Pseudorandom code. This code has the property of never repeating itself.This code is unique. That means, user encrypts its signal using this code and code is changed time to time. Thus it is not possible to intercept the users signal.

WebApr 12, 2024 · Bluetooth transmits data on the 2.4 GHz spectrum, while modern WiFi routers allow devices to connect at the 2.4G Hz or 5 GHz spectrum. Bluetooth might interfere with WiFi transmission on the same spectrum if both transmission paths are less than 10 meters from each other. WebJan 31, 2024 · Used in Wireless Networking Devices like Wi-fi, and Bluetooth. DSSS (Direct-Sequence Spread Spectrum) In DSSS (Direct-Sequence Spread Spectrum), the data to be transmitted is first encoded using a “chip code.” The chip code is used to modulate the carrier signal, spreading the transmitted signal across multiple frequency bands.
