The objective of this lab experiment is tolearn the fundamentals of the directsequence spread spectrum and code division multiple address techniques.To get familiar with thedirectsequence spread spectrummodulator and demodulator. And thedirectsequence spread spectrumsystem can be shown as: Figure 1. Di...
The methods for spreading the bandwidth of the spread-spectrum transmission are (1) frequency-hopping spread spectrum (FHSS), (2) direct sequence spread spectrum (DSSS), (3) pulsed-frequency modulation or chirp modulation, and (4) time-hopping spread spectrum. The last two types are not allow...
What Does Direct Sequence Spread Spectrum Mean? 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 ...
the processing gain and the coding gain can be used to enable many DS spread spectrum signals to occupy the same channel bandwidth, provided that each signal has its own pseudorandom (signature) sequence. Thus it is possible to have several users transmit ...
Direct-Sequence Spread Spectrum in the Microwave Landing System We examine the performance of a direct-sequence spread spectrum (DS-SS) code-division multiple-access (CDMA) system used in a spectral overlay mode in the Microwave Landing System (MLS) band, from 5091-5150 MHz. The purpose of th...
